The biggest threat for organizations in remote work is reduced data security. Office systems are connected to an internal server and which will be protected by high-end security systems preventing unauthorized internal or external access. But this security cannot be assured when a large number of employees working at homes on their own computers, connecting the data via various ISPs. Cloud services come for help here as they allow employees to connect the office data via a secured and centralized server which is multiple times more secure than the office servers. Every data transaction is verified and recorded to ensure absolute data security.

But when data transfer is applied via a cloud solution, an unlimited size of data can be transferred to the client within no time. Cloud solutions redefine the data transfer as with cloud employee and client is accessing data in real-time on a cloud. 

• Increases productivity

It has been proved that remote work boosts employee productivity. Work from eliminates tiresome up and down commuting, busy traffic, strict office timings, etc. employees can complete their tasks when they feel good at the warmth of the home environment. They can save a lot of time which otherwise would have been spent on traveling.

Key Reasons that Add Importance to DevOps Services

The following are some of the reasons as to why DevOps services are considered important for an organization:

Easy and quick development

DevOps as a term as mentioned earlier is a collaboration of development and operations. When the two services work individually, there occurs a delay and lack of achieving desirable results. On the other hand, when the two services are combined, it produces better and greater results. This enables the organization to stay ahead of its competitors in the longer run. These services ensure effortless working as well, no matter how competitive the atmosphere is. 

Low risks and easy recovery

Since DevOps use the most advanced technology, the chances of mistakes and rework is completely cut down. Here, the defective codes in the program are immediately spotted and rectified which reduces the time taken for testing. Also, the developers feel a lower pressure on their work while using DevOps because they do not need to rework on the entire application and only correct the defective area. This helps the users overcome their challenges in operations with the use of such an enhanced technology.

Enhanced creation and collaboration

DevOps helps the users work on a more productive basis by collaborating and combining outputs easily. It allows a group of people to easily work together on a single platform, thus making the tasks at hand simplified. This helps in producing better results than what can be achieved by working independently. On the whole, it helps people in progressing and attaining their goals in a much better manner.

Improved working

When the huge tasks are split into smaller ones using DevOps, the chances of making errors is reduced considerably. Also, improved assistance of technology produces bigger, better results than what is made manually. Similarly, the time taken by the developers in eliminating and replacing the errors can be utilized fruitfully for some other purposes. Parallel activities taking place at a time also reduces the time gap taken for the completion of the project.

Affordable and budget-oriented

DevOps cost marginally very less than what each step incurs individually. It is, in fact, one of the platforms that consists of many user-friendly features that make the user feel completely benefitted from using it. The time and cost incurred in finding a problem, fixing it, and delivering it is half of what is taken manually. This is the main reason as to why users prefer going for the same, disregarding any other aspects.

These are some of the many reasons as to why DevOps has been gaining popularity amongst the users. Due to the benefits and quick results that they produce, users prefer sticking to it, to stay at the forefront of the technology race. Support Monk provides the best DevOps services in Kochi.

Benefits of DevOps Services in a Business

The following are some of the best benefits incurred when a business organization uses DevOps services:

Speedy delivery

The best benefits of DevOps are that they are fully automated, evicting half the concerns of its users. This makes the process of creation, delivery, and feedback, way quicker, and avoids unnecessary delays. As a result, the organization is made all the more systematic and responsive to meet the requirements of its users. Ultimately, these reduce the time taken by a firm in getting in touch with their client.

Cost-effective

DevOps is one of those platforms where any task can be repeatedly done without any financial loss. It takes immediate and assured actions that are a solution to the crisis being faced. Therefore, the costs borne in automotive testing can also be slashed down easily. Hence, the time gap spent in resolving the downtime or the time when systems become dysfunctional is minimized. This results in the organization acting immediately responsive to the business requirements, satisfying the customers.

Easy collaboration

DevOps are one such service that makes the work of an organization lesser by splitting and assigning responsibilities. This results in the reduction of workload and adds to the quality of work submitted by each member of the organization. Also, the workflow gets to be more systematic and developments also become a lot more visible. Besides, interdepartmental communication gets strengthened and there is an active and more productive environment created. Here, each member of the firm becomes active when given equal and significant responsibility during work.

Zero defects

Testing is said to be one of the worst parts before the deployment of software. DevOps find the best possible solution to eradicate errors before the delivery of service. Thus, the employees feel more confident and create an efficient workflow which turns out to be merit to the firm. Later, this software is also tested and monitored to check whether they meet the users’ requirements or not. This not only ensures high quality to the end product or service but also ensures complete user support.

Supports any business

DevOps is one of those services that add to the savings of the users during the business. It uses the most sophisticated and innovative technology that befits the requirements. The technology used in DevOps is said to be most profitable for the rapid development of smaller software that yields bigger benefits. In short, it means that this software helps in the overall improvement of sales, production, and a well- planned work structure.

DevOps is one such factor that is often ignored and if added, improves in the success of the requirement. Using the same and getting it tested for automation before delivery increases its quality by far.

Need for Docker and Kubernetes Support
The following are some of the reasons as to why Docker and Kubernetes support are considered essential:

1. Ensures better resource management
   Most containers are usually capacitated to comprise only a certain amount of data. In many cases, organizations are found investing lumpsum on them and end up in the loss of the most vital information. The cost of dockers may vary depending upon the data storage requirement, but these are said to be totally worth the investment. Kubernetes, on the other hand, assists the users with a list of tools that help the users with the storage, measuring, and updating of the data. This ensures the resources to be effectively used.
2. Quicker software delivery
   Software always undergo quick updates and need to be responsive to the requirements of the users. Docker allows the software to be installed and updated quickly and easily, without affecting the documents of the user or his deployments. Also, this platform allows the user to go back to the previous versions and switch easily. This is the same in the case of Kubernetes where the integration, installment, and delivery do not affect the software. These can be altered and managed according to the need and nature of the organization, to meet their requirements.
3. Makes Portable Applications
   What matters the most in using an application is the safety and easy access of the data that has been stored within. Dockers are platforms that are enabled to contain files of huge capacity and are adaptable to the user’s requirements. With a docker availed, an organization and its users can easily handle their documents remotely. Kubernetes help with the easy updation of these files, no matter how huge they are, or contain links, texts, or commands within them.
4. Self-control mechanisms
   Dockers come with a perfect feature of control and access permission mechanisms. Whenever it is used in a network, it handles the data in it accurately and has got a memory to manage the applications within. These can be easily run on any kind of OS platforms and take half the expected time to be installed. The same is the case of Kubernetes where the files can be controlled, maintained, and the versions can be easily saved. Also, both Dockers and Kubernetes allow any files to be removed and replaced with the originals anytime.

Check whether the partition is on the ext4 filesystem or not. Ploop doesn’t work on ext3 filesystem. My node’s /vz partition was on the ext3 filesystem.

We cannot simply upgrade the /vz partition from ext3 to ext4 as lots of VPS are running on it. Here I have checked the vzctl version and found it was the latest one 4.7.x

# vzctl --version
vzctl version 4.7.1

The latest vzctl tries to create a template as ploop which is advanced than simfs. Since the partition runs on the ext3 filesystem, the safest way to fix the issue is to downgrade the version of vzctl to 4.5.x

version 4.5.1 is not available in OpenVZ anymore. You may need to manually download the rpm of vzctl and vzctl-core from https://openvz.org/Download/vzctl/4.5.1 and install it.

Before installing it, remove the current vzctl 4.7.x

# yum remove vzctl
# cd /usr/src
# wget http://download.openvz.org/utils/vzctl/4.5.1/vzctl-4.5.1-1.x86_64.rpm
# wget http://download.openvz.org/utils/vzctl/4.5.1/vzctl-core-4.5.1-1.x86_64.rpm

You can check this through command line itself, run the following in nagios server.

# /usr/local/nagios/libexec/check_nrpe -H hostname/clientserverIP -c check_load
CHECK_NRPE: Error – Could not complete SSL handshake.

You may need to cover different scenarios for this to troubleshoot.

1) Check if the particular check is available in client server (For example, check_load, 3ware_check, mail_count etc)

2) Check if xinetd or nrpe stopped running,otherwise try to restart it.

# /etc/init.d/xinetd restart
# /etc/init.d/nrpe restart

3) Make sure you allowed the nagios IP in /etc/xinetd.d/nrpe if nrpe is running under xinetd,like as getting in netstat result.

# netstat -plan | grep :5666
tcp 0 0 0.0.0.0:5666 0.0.0.0:* LISTEN 25022/xinetd

Check the parameter “only_from” in this file whether allowed nagios IP there.

Then restart xinetd

# /etc/init.d/xinetd restart

OR

Make sure you allowed the nagios IP in /etc/nagios/nrpe.cfg if nrpe is not running under xinetd and as nrpe user itself, like as getting in netstat result.

# netstat -plan | grep :5666
tcp 0 0 0.0.0.0:5666 0.0.0.0:* LISTEN 248184/nrpe

Make changes to value of parameter “allowed_hosts” in /etc/nagios/nrpe.cfg to as shown below

allowed_hosts=127.0.0.1,nagioserverip

Then restart nrpe

# /etc/init.d/nrpe restart

4) Try to whitelist nagios server IP in firewall.
