Hence, it will be a great opportunity for you to get in-depth knowledge in this by joining DevOps Training in Chennai.
What do you mean by Continuous integration?
It is considered to be a very important feature as this defines the process of auto generation. In this every individual will be integrating the software code at least once a day followed by the verification process.
What do you infer from Canary Release?
It is an arrangement, which cuts down the possibility of prefacing latest version of the available software in production. This process is accomplished by composing it accessible to the user in a composed way.
In this, team gives access to a particular set alone among the complete subsets of infrastructure. In addition, user’s request is not routed. Now, after this when the entire team is satisfied with the test performance, the process of routing is initiated among selected group. Our trainers will give you the complete information related to DevOps Course in Chennai.
Benefits of Canary release:
- It either ramp-up or ramp-down the process of monitoring.
- Capacity testing is done
- The rollback strategy is considered to be very safe.
- Management of multiple software simultaneously is not possible.
- The processing over a distributed network is difficult.
List some of the advantage of Continuous Integration.
There are many benefits of continuous integration such as:
- Software is movable at any point of time. If the developer is able to get the feedback immediately then the count of issues arising will be reduced to a great extent.
- The quality of software gets boosts up as the defects present in the software is eradicated.
- Responsibility of the code is recorded.
- As the whole process of testing and inspection is done in an automated manner. Hence, it is easy to track easily.
What do you mean by Design Pattern?
It acts as solution for numerous problems experienced by the software developers. This is considered a best tradition that is followed by the developers. In addition, they aid the unaccustomed developer in learning the process in a swift manner as they have some sort of standard terminologies.
The various types of design patterns available are:
- Structural – it helps in the simplification of relationship amidst objects.
- Creational- this addresses almost all the problems related to design.
- Behavioral- it aids in the simplification of the process of interaction of objects.
Define blue or green deployment pattern.
It is considered to be one of the challenging issue experienced during the deployment in an automatic manner. In this the team makes sure the presence of two production environments that are identical in nature and one among the two is made LIVE.
The environment, which was made LIVE is treated as Blue environment the team conducts the finalized testing while preparing for the next release that is treated as Green environment. Now, some sort of tool is deployed for directly sending the user’s request to the environment that is Green whereas Blue is kept idle. The user will be able to switch amidst the two environments. Thus, DevOps Classes in Chennai will be of good scope for you.
- It consists of stand-by node for production that is under running condition.
- Availability of rollback is an added advantage.
- Rollback testing is done for every new release.
- The maintenance cost of two environments for production is bit high.
- Refactoring of database is difficult to be handled.
Explain two-factor authentication.
It is a type of security process that enables the user to have two-way authentication. In this one end has a token or card and the other end needs to be some sort of code that has to be memorized by the user in order authenticate. Hence, DevOps Course in Chennai will get you information in abundance related to it.
Is it possible for sharing any single instance of Memcache amidst multiple projects?
Sharing of single Memcache among various projects is certainly possible. Moreover, it acts as a storage space along with execution of it over multiple servers.
The user can enable a person to speak any particular instance. Thus, making it to be executed over multi process of Memcache on any particular host and making sure that both are independent of each other.
How should Memcache not be used?
- It should be made use as a cache rather than data store.
- User should make use of various sources in order to gather the information and not dependent on Memcache alone for the execution of application.
- There is no security present in Memcache for both encryption and authentication.
- Moreover this acts just as key whereas performance of query cannot be done over data.
How is it possible to minimize server outage in Memcache?
- Coding helps in reducing the server outage along with giving the liberty for changing server list in Memcache.
- Setting up of timeout, value is a great option in order to keep in control server outage.
- During the failure of any instance, coding can be deployed for the minimizing of this cache stampedes.
Why to make use of DevOps?
Companies are making use of numerous strategies for in order to satisfy their customers on a whole. In order to attain this companies need to adopt:

Technical innovations in DevOps
In order to know whether this article is useful for you or not, you must get some idea over DevOps Training in Chennai. DevOps is neither a tool nor a software but it is the platform, which enables developer and tester to work on the same page. Some of the latest tools in the market in the year 2018 are listed below:
- ELK STACK
An open-source management tool administers the automation of apps along with infrastructures in IT like the configuration of network and deployment of clouds. It works on master-slave architecture, which is agent-free with the usage of simple syntax in YAML.
A continuous integration, which is written in the Java language. It can be used for the testing purpose in real-time, which aids in finding a solution for bugs. Jenkins provides multiple ways of communication. The scripts can be pipe lined into a single workflow. Integration of your DevOps stages can be done with around 1000 plugins.
An open-source tool used for configuration, also used in the inspection and deliver the software across the lifecycle that is independent of platform. Puppet is working over master-slave architecture, which maintains a long record of accomplishment.
It has a powerful monitoring system that provides an identity to the organization along with the resolving the issues of infrastructure. Monitoring of server performance issues and planned infrastructure upgrades prior to the outdated systems.
It is a combination of Elasticsearch, Logstash and Kibana, which is used in the collection of insights of logs or data. It is lightweight and simple for deployment along with the search for performance in real-time.
What do you infer from DevOps?
It is a refinement that promotes the combination between the teams of Development along with Operations in order to deploy code for increasing the production in an automated way.
DevOps aids in the increase of any organization’s overall speed for delivering various application along with various services on time. It enables the organizations to dish out the applications to customers in a better and satisfactory manner in the market. The word ‘DevOps’ is a blend of two words that are ‘development’ and ‘operations.’
In other words, DevOps is an arrangement of both development along with IT operations along with improved communication and combination. FITA is a great place to get DevOps Training in Chennai.
Why is there need for DevOps?
- Prior to the innovation of DevOps, both the teams of development together with operation were working in a completely isolated environment.
- Both Deployment and Testing were totally isolated activities that is done after the process of designing, which consume a lot of time than the real build cycles.
- Without deploying DevOps, the members of the team are allocating a lot of time in the process of testing, setting up, and designing which is alternative of building the project.
- Deployment of code manually leads to various human mistakes during the production.
- Both the teams of operation along with the team of coding have their own timelines to be met and are not in always in sync which causes further delays.
Why is DevOps used?
The demand for DevOps is considered to increase the estimated time of software delivery by business shareholders. DevOps acknowledges the Agile Development team for the implementation of Continuous Integration along with Continuous Delivery. It also aids them to send off products in a swift manner into the market. Some of the important reasons for the use of DevOps are:
Standardization: This offer necessarily lower amount of failure rate for the new releases.
Recreation: It is very simple to restore the earlier version at any point of time.
Maintainability: The recovery process is easy in the process of any new release that disables the prevailing system.
Minimal Risk: DevOps includes various security aspects in software delivery life cycle. This also helps in the reduction of defects over the life cycle.
Dish out to market: DevOps saves the time to market over 50% through the streamlined software delivery. In particular the case of both mobile and digital applications.
Good Quality: It aids the team in order to provide enhanced quality of various application development as this incorporates all the infrastructure issues.
Resiliency: The software system is extra stable in operational state with more secure, and auditable changes.
Cost Efficient: DevOps is cost efficient in the field of software development that is always a goal of the IT company’s management.
Future of DevOps
There are numerous technology developing on a daily basis for making our life simple and easy to live. DevOps is making the same process in the development of software, as this brings together both development and operation. Thus, it has a great scope in the future. FITA is ranked as the best institute for DevOps Course in Chennai.
As the process of evolution is keeping itself updated, organizations are making their targets to be accomplished within weeks and months instead of extending it to years. The access of DevOps engineer will extend in the controlling of end user in the near future.
When to use DevOps?
DevOps can be made use of when large allocated applications like eCommerce sites are hosted on cloud platform.
Lifecycle of DevOps
DevOps has a deep integration amidst the process of development and operations. Learning DevOps is impossible without having the in-depth knowledge in DevOps lifecycle.
The occurrence of development of software is in a consistent manner. In this stage, the complete process of development is fragmented into miniature development cycles, which acts as a perk to the DevOps team in order to quicken the software development process along with delivery.
The quality team makes use of various tools such as Selenium in order to identify along with fixing the bugs in new piece of code.
In this phase, new functionalities are unifies with current code, followed by testing. Continuous development is possible only due to the continuous integration along with the process of testing.
- Line up
The deployment process is a continuous process that is performed so that any changes made at any point of time in code, will not affect the functioning of website.
The team handling operation will be held responsible for any inappropriate system behavior that occurs in the production.
For further information on DevOps join our DevOps Certification in Chennai.
Workflow in DevOps
It provides a visual analysis of the sequence where input is provided. This also tells about the actions that are performed, along with the output generated for any operations process.
Workflow enables the fragmentation along with arranging various jobs that are top-requested by users and also gives ability to replicate their optimal process in configuration of jobs.
Principles of DevOps
There are 6 principles that are considered as essential while selecting DevOps:
- Customer-Centric: The team of DevOps must consider customer’s action more important as they are the consistent investors in the products and various services.
- End-To-End Responsibility: It is necessary in order to provide performance aid until they evolve into the end-of-life, which enhances level of the responsibility along with quality of the various products engineered.
- Continuous Improvement: DevOps culture target on the continuous improvement for minimizing the waste and speeds up the improvement of services offered in a consistent manner.
- Automate everything: It is the most important principle of the process in DevOps, which is not only for the process of software development but also for complete infrastructure landscape.
- Single team: In DevOps role of the tester, developer, and designer are already specified. All they need to do is work as a single team with total blend.
- Monitoring and testing: It is very crucial for DevOps team in order to have a strong monitoring along with all the procedures required for testing.
Who is DevOps engineer?
They are IT professional and work as software developers, operators, along with the various production IT staff for administering the code releases. They must have both hard and soft skills in order to communicate and blend with testing, development, and operations teams.
DevOps technique requires frequent changes for code versions that mean frequent development and testing procedure. Even though DevOps engineers are expected to code occasionally from scratch and are important that they should have basics of software development languages.
They will be working with the development team staff in order to tackle coding and scripting for connecting the elements of code. DevOps Training in Chennai will enhance your skill in DevOps.
Roles and responsibilities of a DevOps Engineer
DevOps engineers are responsible for both the production and ongoing maintenance of a software application.
Few of the expected roles and responsibilities expected from DevOps engineer are:
- They are able to perform troubleshooting and various problem-solving for a system across the various application domains.
- These are the people who manage all the projects effectively through open and standards-based platforms.
- They increase visibility of project thought trace ability.
- DevOps Engineer improve the quality and reduce cost of development with collaboration.
- They analyze, design along with the evaluation of the automation scripts & systems
- Theses engineers ensure critical resolution of every system issues by making use of the best cloud security solutions for all the services.
- They are considered to have the soft skill of a problem-solver along with being a quick-learner.
DevOps Automation Tools
It is very crucial to automate all the testing processes and also configure them in order to achieve both speed and agility, which is called as DevOps automation.
There are certain difficulties faced by large DevOps Team that maintain huge IT infrastructure which can be categorized into six categories:
This process of scripting environments begins from installing operating system, to installing along with configuring servers, and establishing software communicate with one another. In this the user can apply same configuration to single node or to multiple nodes.
It is also known as IT management, scripting infrastructures, configuration management, provisioning, and system configuration management. The overall matter is similar here description of infrastructure along with its configuration as script is replicated with minimal error. This also adds agility for both the development and operations process as this can be modified by any team in future.
In the past few years, emergence of several open source and commercial tools has been consistent in order to support the infrastructure automation. Some of the open source tools are Puppet, Bcfg2, Chef, and CFEngine, which can be used in both virtual and physical environments along with cloud.
The infrastrcucture automation tools Chef and Puppet make use of Ruby domain-specific language (DSL) for the purpose of scripting environments. In this, Chef is expressed as internal Ruby DSL, whereas Puppet users use external DSL. These are more often made use in Linux system automation but also support Windows. With the help of Puppet, user is able to set dependencies on various tasks. DevOps Course in Chennai will lend you a helping hand in this technique.
The Chef tool supports various platforms such as Ubuntu, RHEL/CentOS, Debian, Mac OS X, Fedora, Windows 7, and Windows Server. There are many leading organization that make use of Puppet namely, Google, Rackspace, Twitter, and Oracle for managing their infrastructure.
Configuration management serve as the true source of configuration items, which can be configured and is absolutely important for success of any project. When considering both software development and management, the term configuration management implies to the item that is to be configured along with management for the success of the project.
This can have many connotations that depend on the person who’s discussing it. In the software development industry it is referred to as the source code management. But, there is a much more to configuration rather than managing source codes in DevOps.
This process considers the following set of activities:
- Configuration identification
- Configuration control
- Configuration audit
Configuration management plays a very crucial role as this enables ability to sequence both infrastructure and software systems beyond having to scale administrative staff in order to manage the system. Configuration management in DevOps consists of the following elements:
Source Code Repository — Used during the development phase.
Artifact Repository — Used for both development and operations stage.
Configuration Management Database — Used in both the process of development and operations.
Generally, many consider log management as a tiresome works as each instance of the new server requires to run any search command beyond logs local to the specific server. With the reduction of the cost spent and increase in the prevalence of containers along with virtual systems, number of systems executed within any typical organization raises exponentially along with the prosperity in the business. There are three pillars present for the observability:
- Metrics and Distributed Tracing
- External Monitoring
- Events and Log
There are numerous tools deployed in the DevOps techniques for the ease of the accomplishment of the process. Some of them are enlisted below:
- Linux Admin
It is an open source IT engine for the automation of application deployment along with intra service, and cloud provisioning. It makes use of playbook in order to describe the various automation jobs, where playbook uses simple language such as YAML.
Working of Ansible
It is designed for the multi-tier deployment but does not manage one single system at a time. Ansible is free from agent that means this works by connecting nodes through SSH followed by the execution of the modules, and finishes by the removal of them.
The advantage of Ansible is it removes the modules after the installation and also connects to the host machine followed by the execution of the instructions. Once it’s successfully installed the code is removed that was copied on host machine.
Common words associated with Ansible
- Target machine
Bugzilla is open-source tool deployed for the purpose of tracking down the bugs and various issues of project. It aids developers and stakeholders in keeping track of the outstanding problems associated with the product. This tool can be made use as a Management tool for testing purpose as it can be linked with ease with the other test case management tools such as Quality Centre, ALM and many more.
There are many advantageous side of deploying Bugzilla, some of them are listed below:
- It is considered as a very powerful tool with latest searching capabilities.
- It also supports the user in configuring email notifications during the occurrence of any changes in the bug status.
- Bugzilla helps the user to get the overall history of bug.
- Bugzilla brings inter bug reliance track along with graphic representation.
- This allows the users to adhere Bug supportive files along with its management.
- It consists of product-based, integrated, granular security schema, which makes it further secure.
- Bugzilla supports Web, , E-Mail, XML along with various console interfaces.
- And it also supports localized web user interface.
- It is expected to have 4 GB RAM or above.
- It should consist of a Fast Processor, at least 3GHz or above.
Bugzilla needs a web server, database server, along with Perl.
Perl − Bugzilla 4.4 and older requires Perl 5.8.1 or above, but Bugzilla 5.0 and newer will require Perl 5.10.1 or newer. It is not advised to install Perl 5.8.x at this stage. You can try to install Perl 5.12 or newer, as both of them are newer versions and consist of some useful improvements.
Database Server – This supports MySQL, PostgreSQL, Oracle along with SQLite. MySQL and PostgreSQL are highly advised, as they have best support from Bugzilla and are used on a regular basis by Bugzilla developers.
