The Internet of Things (IoT) has steadily transformed the way daily duties are completed. Take clever homing for example. People can start their cooling devices remotely thru their mobile phones. This in advance was once viable through an SMS, but nowadays the net has made it less difficult. Apart from supplying smarter solutions for houses and housing communities, IoT has additionally been used as a device in enterprise environments across numerous industries. However, with the number of large records, this is generated with the aid of IoT, a whole lot of stress is placed on the internet infrastructure. This has made businesses and companies search for a choice that might reduce this load.
Enter cloud computing- an on-call for delivery of computing energy, database garage, applications and IT sources. It enables businesses to devour a computer resource, like a digital gadget (VM) instead of building a computing infrastructure on premise.
Today, cloud computing has greater or much less penetrated mainstream IT and its infrastructure. Many tech biggies which include Amazon, Alibaba, Google, and Oracle are constructing device studying gear with the assist of cloud era to offer a huge range of solutions to businesses globally. This article objectives to tell you about the role of cloud computing in IoT and why IoT and cloud computing are inseparable.
How IoT and cloud complement each other
Cloud computing, as well as IoT, work closer to growing the performance of everyday tasks and both, have a complementary relationship. On one hand, IoT generates masses of records even as however, cloud computing paves way for this statistics to tour. There are many cloud carriers who take gain of this to offer a pay-as-you-use version wherein clients pay for the precise assets used. Also, cloud hosting as a provider provides value to IoT startups by supplying economies of scale to lessen their universal fee shape.
In addition to this, cloud computing also enables higher collaboration for developers, that’s the order of the day within the IoT area. By facilitating developers to store as well as get admission to data remotely, the cloud allows builders to implement tasks straight away. Also, through storing information within the cloud, IoT groups can get right of entry to a huge amount of Big Data. So, in a bid to lay down the connection between IoT and cloud, here’s a table so one can permit you to understand how they suit every other like a glove.
| Parameter | Internet of things | Cloud computing |

Why is Cloud essential to the success of IoT?
Just like cloud computing is constructed on the tenets of velocity and scale, IoT packages are built on the precept of mobility and significant networking. Hence, it’s far critical that both cloud and IoT shape cloud-based IoT packages in a bid to make the most out in their mixture. This alliance has brought about the achievement of IoT. In addition to this, right here are some greater tips as to why the cloud is important from the point of view of IoT’s achievement.
Provides faraway processing electricity
Cloud as a generation empowers IoT to move beyond everyday appliances along with air conditioners, refrigerators and so forth. This is because the cloud has the sort of tremendous storage that it takes away dependencies on on-premise infrastructure. With the upward push of miniaturization and transition of 4G to better net speeds, the cloud will permit builders to dump speedy computing methods.
Provides security and privacy
IoT’s role in harnessing mobility is mammoth. However, its prowess would be incomplete without safety. Cloud has made IoT more cozy with preventive, detective and corrective controls. It has enabled customers with robust safety features via offering effective authentication and encryption protocols. In addition to this, coping with and securing the identity of customers has been feasible for IoT products with the assist of biometrics. All of this is feasible due to cloud’s safety.
Removes access barrier for web hosting companies
Today, many innovations within the discipline of IoT are searching at plug-and-play website hosting services. Which is why the cloud is a great healthy for IoT. Hosting provider ought no longer to rely upon massive gadget or even any form of hardware so that it will not help the agility IoT devices require. With the cloud, maximum website hosting vendors can allow their clients a prepared-to-roll model, doing away with entry limitations for them.
Facilitates inter-device communication
Cloud acts as a bridge within the shape of a mediator or communique facilitator on the subject of IoT. Many powerful APIs like Cloudflare, CloudCache, and Dropstr are enabled by way of cloud communications, allowing easy linking to smartphones. This eases gadgets to speak to every different and not just us, which essentially is the guideline of IoT cloud.
It could be honest to mention that cloud can accelerate the growth of IoT. However, deploying cloud technology additionally has certain demanding situations and shortcomings. Not because the cloud is flawed as a technology however the mixture of IoT cloud can burden users with a few barriers. If you ever pass in advance with an IoT cloud solution, it is higher if you recognise the sort of demanding situations you may face in advance.
What are the challenges posed through cloud and IoT collectively?
Handling a huge quantity of information
Handling a large amount of records can be overwhelming particularly while there are thousands and thousands of devices in the photograph. This is due to the fact the general performance of applications is at stake. Hence, following the NoSQL motion may be useful, however it isn’t always attempted and examined for the long term. Which is why there exists no sound or fool-evidence technique for the cloud to manage big records.
Networking and communique protocols
Cloud and IoT involve device-to-gadget communications among many special sorts of devices having numerous protocols. Managing this kind of a variation may be tough on the grounds that a majority of application regions do now not contain mobility. As of now WiFi and Bluetooth are used as a forestall-gap strategy to facilitate mobility to a positive extent.
Sensor networks
Sensor networks have amplified the advantages of IoT. These networks have allowed customers to degree, infer and understand delicate indicators from the surroundings. However, well-timed processing of a massive amount of this sensor records has been a main assignment. Though cloud offers a brand new possibility in aggregating sensor records it additionally hinders the development because of protection and privacy issues.
Conclusion

Enterprises deploying cloud hosting needed storage solutions that can help them manage critical business data. With the rise of open source software and high-performance storage systems, their penetration into cloud technology became imminent. Underlining this principle of high-performance storage systems for fast compute speed, Ceph storage was formed.
What is Ceph Storage?
Ceph is an open source software put together to facilitate highly scalable object, block and file-based storage under one whole system. The clusters of Ceph are designed in order to run commodity hardware with the help of an algorithm called CRUSH (Controlled Replication Under Scalable Hashing). This algorithm ensures that all the data is properly distributed across the cluster and all cluster nodes can assimilate as well as retrieve data quickly without any constraints. Think of Ceph this way- you have a large amount of data that can be sorted into clusters as well as subclusters. Now, the subclusters have to be a part of a cluster so that the right information belongs to the right lineage. Enter CRUSH, a scalable hashing algorithm which helps you divide the data into the right clusters as well as subclusters. This data, properly slotted can be retrieved as and when one wants. Thus, Ceph can not only store large amounts of data but also simplify access to the same.
Hope this answers your question to- What is Ceph storage? In addition to this explanation, the article aims to give you a complete understanding of the working of Ceph storage, its features, advantages and why is it used. So, let’s dive in and know more.
How does Ceph storage work?
Ceph uses Ceph Block Device, a virtual disk that can be attached to bare-metal Linux-based servers or virtual machines. RADOS (Reliable Autonomic Distributed Object Store), an important component in Ceph, provides block storage capabilities like snapshots and replication which can be integrated with OpenStack Block Storage. Ceph also makes use of POSIX (Portable Operating System Interface), a Ceph file system to store data in their storage clusters. The file system uses the same clustered system as Ceph block storage and object storage to store a large amount of data.
On the whole, Ceph’s functioning as a storage system is quite simple. Hence, it is deployed by many hosting and IT solution providers for their clients.
What are the features of Ceph storage and why do we need it?
Since data is growing at an exponential rate today, organizations need a solution that can store large data volumes effectively. This has been a major challenge. Ceph storage is an effective tool that has more or less responded effectively to this problem.
In addition to this, Ceph’s prominence has grown by the day because-
1) Ceph supports emerging IT infrastructure: Today, software-defined storage solutions are an upcoming practice when it comes to storing or archiving large volumes of data. One of the prime reasons for this being legacy infrastructure and solutions cannot meet the storage needs at a reasonable cost. Moreover, with cloud technology being increasingly leveraged by IT organizations, providing a solution as befitting becomes necessary. All these factors have helped Ceph steal an important spot when it comes to new infrastructure.
2) Ceph provides dynamic storage clusters: Most storage applications do not make the most of the CPU and RAM available in a typical commodity server but Ceph storage does. Right from rebalancing the clusters to recovering from errors and faults, Ceph offloads work from clients by using distributed computing power of Ceph’s OSD (Object Storage Daemons) to perform the required work.
3) Ceph is scalable, reliable and easy to manage: Ceph allows organizations to scale without affecting their Cap-ex or Op-ex. A Ceph node leverages commodity hardware and intelligent daemons along with Ceph Storage Clusters which communicate with each other to replicate and redistribute data dynamically. These nodes are monitored by Ceph monitors to ensure their high availability.
To put it in a nutshell, Ceph has transformed IT organizations when it comes to data storage.
How is Ceph storage beneficial for web professionals and how can they make the most out of it?
Ceph runs on any commodity hardware without any vendor lock-in. As a software-defined storage solution, it provides flexibility in hardware selection as well. This has made it quite popular among web professionals. In addition to these benefits, Ceph provides many advantages which can be listed as follows:
a) Data safety – Ceph makes each data update visible to clients. In addition to this, they also let users know that this updated data is safely replicated on a disk and will survive power or other failures. Moreover, RADOS dissociates synchronization from safety while acknowledging updates in a bid to allow Ceph to realize low-latency updates for app synchronization and data safety semantics. In this manner, Ceph storage ensures data safety for users.
b) Failure detection – Spotting errors or failures at the right time is of essence while securing data. However, this can get difficult with too many clusters on a large scale. OSDs (Object Storage Daemons) can self-report in such cases. If OSDs do not hear of any failures from peers then a RADOS considers two dimensions of the OSD- a) whether it is reachable or b) whether it is assigned data by CRUSH. In case the OSD is not responsive, it gets marked down and any primary responsibility that it holds is passed to the next OSD on a temporary basis. Thus, Ceph monitoring detects anomalies, if any, in a distributive environment. Also, this distributed detection allows quick detection without burdening the monitors while resolving inconsistencies.
c) Cluster recovery and updates – In case of OSD failures, OSD cluster maps undergo changes. In a bid to provide fast recovery, OSD maintains a version number for each object and a log for recent changes. So, for example, let us consider OSD1 and OSD2. If OSD1 crashes and is marked down, its status is updated and OSD2 takes over. Once OSD1 recovers, it will request the latest map on boot and a monitor will mark it as up. This OSD2 realizes that it is no longer required to conduct primary responsibilities and allows OSD1 to take over to retrieve log entries. In this manner, Ceph not only allows data storage to remain safe but also recovers clusters of data quickly.
d) Data distribution & replication – Ceph adopts a simple strategy when it comes to distributing data. Ceph maps objects into PGs (placement groups) using a simple hash function. These placement groups are then assisted to OSDs using CRUSH to store object replicas. This differs from conventional approaches where one has to depend on a lot of metadata, though Ceph also uses metadata in a very small way. Also, when it comes to replication, data is replicated in terms of these placement groups each of which is mapped to an ordered list of OSDs. This distribution and replication have made Ceph a scalable storage solution.
Conclusion
If you look at Ceph as a whole it has addressed three crucial challenges when it comes to storage systems- scalability, reliability and performance. Most importantly, its central tenets- RADOS, CRUSH, and POSIX have made Ceph a holistic storage system. In addition to this, it is also useful in securing cloud storage. We hope that with this article, you have understood what Ceph storage is and why is it preferred by hosting providers and businesses. If you have any queries about -What is Ceph storage? feel free to write about them in the comment section below.
Some of you can already be acquainted with Big Data, they are essential, huge statistics units that are so big and complicated that it’s miles not possible to control them with outdated software gear. It especially denotes the technologies and tasks concerned in records that are rather various, dynamic, or great for conventional technologies to cope with adequately. Fundamentally, it’s approximately extremely dispensed architectures and parallel processing, with the assist of commodity building blocks to manipulate and analyze the records.
In essence, Big Data pertains to developing facts, storage, recovery and evaluation in phrases of extent, velocity, and variety. It refers to scaling out data architectures so one can address new necessities as a long way as information quantity, speed, or variability are involved. Traditional information architectures are sick acceptable for such requirements.

Many web professionals old and new, have always had their share of doubts when it came to WordPress.com vs WordPress.org. Though they may have some points in common there are many differences between the two that can be leveraged in order to make the most out of them. Hence, for any web pro who is serious about leveraging WordPress as a tool to build a website or publish content, it becomes imperative to know the difference between the two. This article seeks to lay emphasis on what is WordPress.com and WordPress.org, what their pros and cons are, what is the difference between WordPress.com and WordPress.org and when can they best be deployed.
What is WordPress.org?
WordPress.org is an open source platform which is free for one and all. Since it is a free software, you can download and install the same on your own web server. With WordPress.org, you can host your own website or blog. Hence it is also referred by many as ‘self-hosted’ WordPress.
What are the benefits of WordPress.org?
Apart from the fact that it is free to download, WordPress.org has quite a few interesting benefits. Let us look at some of the benefits, shall we?
- With WordPress.org, you have total control over your website. Which means you will not be bothered with ‘take this content’ down notifications unless you violate internet rights.
- You can monetize the website by running the ads of your choice, without splitting the revenue.
There is no restriction in terms of downloading a theme for your website. Same is the case in terms of plugins. - Since the website is hosted on your own web server, you can make changes to the directory of the web files as you want.
- You can customize the website as you want and change its design, that too without incurring any costs.
What are the disadvantages of WordPress.org?
- You may require some prior technical knowledge. A sound understanding of HTML will be good to have but not a must.
- Since the website is self-hosted you are responsible for everything right from security updates, backup and support for the website. In addition to this, with WordPress.org, you are not a part of the WordPress network directly i.e as opposed to WordPress.org, WordPress.com makes their users a part of a large community where they explain ways of updating WordPress, provide information for resolving conflicts etc. Hence, promoting the website and marketing the same can be a daunting task.
What is WordPress.com?
WordPress.com is a WordPress hosting service created by WordPress for its customers. If you avail their hosting service, your website will be hosted on their servers. In short, WordPress.com takes care of all your hosting needs.
What are the advantages of WordPress.com?
WordPress.com basically takes away your worries when it comes to hosting requirements. But along with this major advantage, come many other advantages. Let’s see them one by one:
- WordPress.com does not require much investment in terms of time from the user’s point of view. Its setup time is considerably less.
- The overall management of the website is minimal since hosting providers take care of all the services right from file uploads etc. Which means you do not need to access the FTP account or even add domain through a control panel or conduct any such tasks.
- You need not have any technical know-how i.e you don’t need to code or know a coding language etc.
- Since it is a paid service, WordPress.com provides email and chat support to customers. In addition to this, since you are a part of the WordPress community, it can send traffic to your website by featuring your website on its marketplace portal.
What are the disadvantages of WordPress.com?
- WordPress.com allows access to a limited number of themes and templates for their website (only 165).
You do not entirely own the content on WordPress.com i.e, WordPress.com has the right to shut it down. You do not have the right to sell the website or blog without permissions. - The free plan of WordPress.com will provide you with a subdomain i.e your website will read as www.yourwebsite.wordpress.com and not www.yourwebsite.com.
The major point of difference between WordPress.org and WordPress.com is that with the former you download the software whereas with the latter you are provided with an end-to-end hosting service for WordPress. However, it is only by pitting WordPress.com vs WordPress.org, against certain parameters will know which one is a better choice.
Difference between WordPress.org and WordPress.com
Based on some crucial parameters, we have explained WordPress.com vs .org.
| Parameter | WordPress.org | WordPress.com |
|---|---|---|
| Control | WordPress.org gives you complete control over the content as well as the hosting aspects of the website. | WordPress.com the entire control of the website is in the hands of the hosting service. However, you can control which files have to be uploaded by telling your service provider. |
| Theme and Plugin support | Here, you can avail an unlimited number of themes and plugins.You can also avail third party plugins if necessary. | The access to the number of themes and plugins is limited. However, you can purchase themes and plugins with customized plans which could cost you dear. |
| Maintenance | Since the control of the website lies with the user, maintenance of the website is also in the hands of the user. However, this maintenance is not a tall order. | The maintenance of the website completely lies in the hands of the hosting provider i.e WordPress.com. |
| Monetization | Users can freely monetize through the WordPress.org since the platform allows one to create their own monetization models. | WordPress.com enforces stringent policies when it comes to monetization i.e. users need to have a certain amount of traffic on the website to use WordPress’ own monetizing model. |
| Analytics | With WordPress.org, your analytics end can grow more powerful by integrating your website with Google analytics or other powerful tools like KissMetrics, MixPanel etc. | One can avail Google analytics by integrating the plugin with the website only if they avail WordPress.com’s business plans. Else, the analytics come straight from WordPress. |
| Expense | The expense could be higher with WordPress.org since hosting charges, design charges incurred can go well out of control. | The expenses in case of WordPress.com can be mitigated since monthly hosting charges are limited. |
| SEO | With WordPress.org, you can install unlimited SEO features. | With WordPress.com, you can add a limited number of third-party plugins for SEO. |
In closing, we would like to add that WordPress.com and WordPress.org have their own peculiarities. For instance, WordPress.com’s free plans can be best used when you want to have your own free blog. Whereas, with WordPress.org, you can grow your own website as you want by adding more products, services or ads to monetize from. We hope that you have understood the difference between WordPress.com and WordPress.org is crystal clear. In case you have any doubts or queries, feel free to leave your comments below.
So before we start with the steps involved to configure firewall in Linux, first let’s make sure we understand what a firewall is and how it works.
Understanding what a firewall is and how it works:
A firewall is a program that surrounds the interface between a private network and the rest of the big and (usually) bad internet. You can think of the firewall as a gateway. It follows pre-configured rules that allow certain traffic to pass through from the internet to the private network and blocks those that are unwanted and potentially harmful.
Why do I need to configure firewall for my Linux machine? Isn’t it the safer than most other server OSs?
If you have a Linux machine, you are guaranteed a certain level of security by default, courtesy the amazing Linux developer community. Linux systems are generally immune to a majority of viruses and other threats that many other operating systems succumb to. But with the increase in the volume, variety and intensity of cyber threats today, configuring a Linux firewall is quite a necessity.
A step-by-step guide on how to configure firewall in Linux:
Step 1: Beef-up basic Linux security:
While this blog is titled to address firewall configuration, the first step is to ensure that the firewall has all the support it needs with a 100% secure Linux machine. To do this, ensure you have all the latest security updates installed for your version of Linux.
Step 2: Decide how you want to protect your server:
While Iptables is generally where the linux community looks to configure a firewall, there are easier options available that are also free for use. Here are some that we would recommend:
1.ClearOS:
-ClearOS is extremely easy-to-use. It is suitable those who prefer an easy-to-follow UI AND also for geeks who would like to talk to it through the command-line interface
Post a 10-minute installation time, you are asked to reboot and are given all the information and support required to manage your firewall as easily as possible
2.OPNsense:
-OPNsense offers several advanced features not usually found in free firewalls like ‘forward caching proxy’ and ‘intrusion detection’.
-It supports the use of OpenVPN. To know how useful OpenVPN is, read more here
-It uses an Inline Intrusion Prevention System which is a powerful form of Deep Packet Inspection. Here, instead of just blocking an IP address or port, the firewall inspects individual data packets or connections and stops them before they reach the sender if found malicious
3.ConfigServer Firewall (CSF):
-CSF is an advanced firewall suite for Linux systems has the Login Failure Daemon (LFD) process that regularly scans for failed login attempts (or “Brute-force attacks”) on your Server and takes action against the offending IP Addresses very quickly
-CSF can be managed through the Command Line Interface and its front-end is accessible by the root account through cPanel, DirectAdmin and Webmin which makes configuring and managing the firewall very simple
IPTABLES:
Understand Iptables and how it works:
The Linux kernel has the capacity to filter incoming and outgoing packages with a filtering tool known as ‘Iptables’. The Iptables tool is in charge of deciding which packages can come in and go out based on the rules it is configured to follow.
First, how to configure the firewall manually:
Working with iptables manually can be complicated. We have a quick fix at the bottom of our section you can try. Read on for more.
Step 1: Retrieve the Iptables firewall:
Iptables is pre-installed on almost every Linux distribution. You can use this command to retrieve the package:
sudo apt-get install iptables
Step 2: Discover what Iptables is already configured to do by default:
Run the iptable L command
Step 3: You can decide to modify the existing rules or instead start afresh:
To start afresh, run this command
iptables-F
Step 4: Decide which firewall ports to close:
First block all lines of attack by running the following commands:
Block XMAS Packets: iptables -A INPUT -p tcp –tcp-flags ALL ALL -j DROP
Block null packets: iptables -A INPUT -p tcp –tcp-flags ALL NONE -j DROP
Block syn-flood packets: iptables -A INPUT -p tcp ! –syn -m state –state NEW -j DROP
Step 5: Decide which firewall ports to leave open:
Here are some ports you could decide to leave open:
For outgoing connections:
- 80/tcp for HTTP
- 53/udp for DNS
- 443/tcp for HTTPS (secured HTTP)
- 21/tcp for FTP (File Transfer Protocol)
- 465/tcp for SMTP (send emails)
- 25/tcp for Insecure SMTP
- 22/tcp for SSH (secure connection from computer to computer)
- 993/tcp&udp for IMAP (receive emails)
- 143/tcp&udp for Insecure IMAP
- 9418/tcp for GIT (version control system)
For Incoming connections:
- 993/tcp&udp for IMAP (receive emails)
- 143/tcp&udp for Insecure IMAP
- 110/tcp for POP3 (old way to receive emails)
- 22/tcp for SSH (secure connection from computer to computer)
- 9418/tcp for GIT (version control system)
Step 6: Save your firewall configuration
Type the following command to save the settings you’ve configured and restart your firewall:
iptables -L -n
iptables-save | sudo tee /etc/sysconfig/iptables
service iptables restart
Tools to assist you with the iptables configuration:
If this is too complicated for you, you can use tools such as fwbuilder or UFW. Here, we will run you through the UFW Uncomplicated Firewall.
The UFW is a front-end for iptables that makes configuring the firewall easier while working with iptables.
Step 1: Type this command into the terminal to install UFW:
# apt-get install ufw
Step 2: Next, enable the firewall:
# ufw enable
Step 3: enable the default settings.
# ufw default deny incoming
# ufw default allow outgoing
This will deny all incoming connections. To specify which ones to allow – do the following:
Step 4: To allow specific connections. For example, SSH-
# ufw allow ssh
Step 5: ensure the firewall is saved:
# ufw status verbose

There are many uses of email, of which, two critical uses are as professional email hosting for your business and to market to your consumers. Marketing through Email is one of the most cost-effective ways to boost revenue and conversions. Besides, it helps you stay in touch with your customers. It does take a lot of efforts to create a distinguishing email campaign, which is why you might want to keep a kind of backup. An email service provider, or ESP, can help your business create and deliver emails to your specified customer base or niche, and provide profitable results.
An ESP also gives away detailed reports on the result of your email campaign. This report provides you details on the delivery success rates, email read-rates, and link click-through rates. You can even identify the users who performed these actions. Good reporting is one of the most important features that any email service provider could assist you with, after measuring the effectiveness of your email campaigns.
Let’s check out a few things to consider before you choose an Email Service Provider.
Private IP address: The IP address from which the email is shot designates the origin of an email. If your service provider sends your marketing emails via a shared IP address, you’ll receive too many spam complaints which might have been registered against another customer. This could get your shared IP address blacklisted, preventing your emails from being delivered. It would take a lot of time for your email service provide to get the IP off the blacklist. It is, therefore, important for you to ensure that your ESP provides you with a private IP address.
Reputable provider: Every business wants a service provider who’d be there for the long run. Fly-by-night providers might not have close-links or associations with Internet giants like Yahoo!, Google and Microsoft. You want a provider who has associations with these providers so that your emails do not land under spam.
Features: Identify a list of potential email service providers and browse through the list of features they provide. Make sure the one you select provides assistance to your business now and in the future. You don’t need to have a laundry list of features in place, but there are few basic features which you’ll want to have including social media integration, scheduling, convenience, and tracking tools. You want a provider that has invested in some accreditation and authentication tools that give your emails the best chance to land in the intended inbox.
Customer support: Since customer service is paramount to any business, you want a provider that has an excellent support team in place to help you with any questions or concerns. Therefore, your ESP must provide you with both online and on-call customer support.
Infrastructure: Check if your service provider has more than one, secured high-speed internet connections through more than one source. This will ensure reliability in case any of the Internet connections fails or there is a hardware failure.
