Best Practices For Successful Implementation Of DevOps

What is DevOps?DevOps is nothing but the combination of process and philosophies which contains four basic component culture, collaboration, tools, and practices. In return, this gives a good automated system and infrastructure which helps an organisation to deliver a quality and reliable build. The beauty of this culture is it enables a quality for organizations to better serve their customers and compete more effectively in the market and also add some promised benefits which include confidence and trust, faster software releases, ability to solve critical issues quickly, and better manage unplanned work.                                       “DevOps is not a goal, but a never-ending process of continual improvement.”                                                                           Jez Humble Here are the key DevOps best practices that can help you for successful implementation of DevOps.1. Understand Your Infrastructure need: Before building the infrastructure, spend some good time to understand the application and then align your goals to design your Infrastructure and this implementation of DevOps should be business-driven. While understanding infra, make sure you are capturing below components:Cycle Time : Your software cycle needs to be defined in a generic way where you need to know the limitations, ability and if there is any down time then the exact time need to be noted.Versioning Environments: While planning DevOps, always be ready for an alternative solution and versioning your environments helps you to roll out/back your plan. If you are having multiple module and tightly coupled then it requires a clean and neat plan to identify each and every patch and release.Infra as a code: When we say infra as a code it means a solution to addressing both needs – minimizing cycle time and versioning environments can be addressed by capturing and managing your Infrastructure as code. What you built should scalable for a long run.2. Don’t jump start : There is no need to automate the complete cycle in one shot, always take a small entity and apply your philosophy and get this validated. Once you feel your POC is justified, start scaling up now and create a complete pipeline and define a process so anytime you can go back and check what all need to improve and where. All these small success will help you to get confidence internally in your team and builds a trust to stakeholder and your customers.                                                        “DevOps isn’t magic, and transformations never happen overnight”3. Continuous Integration and Continuous Deployment: If  your team is not planning to implement this continuous integration and continuous delivery, then it is not fair with DevOps. Even I’ll say the beauty of DevOps is how frequently your team can deliver without disturbance and how much you are automated in this process. Let’s take a use case: You and your team members are working in an Agile team. In fact, there are multiple teams and multiple modules which are tightly coupled  in which you are also involved. Every day you work on your stories and at the end of the day, you push your ‘private build’ of your work to verify if it builds and ‘deliver’ it to a team build server and same applies to other individuals. Which indicates you all ‘integrate’ your work in the common build area and do an ‘Integration Build’. Doing these integrations and builds to verify them on a regular, preferably daily basis, is what is known as Continuous Integration.Continuous Deployment doesn’t mean every change is deployed to production as soon as possible. It means every change is proven to be deployable at any time.  What it takes is your all validated feature and build from CI and deploys them into the production environment. And here we can follow some of the practices. a) Maintain a Staging Environment that Emulates Production b) Always deploy in staging then move to production c) Automate Testing of Features and Nonfunctional Requirements d) Automatically fetch version-controlled development artifacts.4. Define Performance and do benchmarking : Always do some performance testing and get a collective benchmarking report for the latest build shared by your team because this will only justify the quality of your build and the required infra as well.For example : We have done one performance testing a few days back and got good results, explaining in details. So we did some benchmarking for our CFM machines because we are having a global footprint and at the same time, for us, latency matters and we need CFM in the nearest region. We have verified with our current build how many requests we can handle and we found we are firing more than 200 RPS (request per second). So we planned to check our build capability and fired a good number of requests and noted the number where our build got crashed and noted the RPS and then we did autoscaling of CFM. We might have upgraded our CFM but we planned for auto scaling because the number of requests is an assumption and we don’t want to spend amount for that but at the same time we are ready to consume the experimented traffic. And then we found 7 out 2 CFM are only consuming exact or little less number configuration and request (181 to 191 RPS). So we shared a report to the business team to focus on other regions where we were having very less traffic because we were paying the same amount.Conclusion: We verified our build which has given good confidence to our dev team and we shared the report to the business team which helped them to plan their marketing strategies, meanwhile we completed auto scaling the process as well.  5. Communicate and Collaborate : Collaboration and communication are the X-factors to help organisation grow and assess for DevOps. Collaboration with business and development team helps DevOps team to understand to design & define a culture. This helps to speed up the development, operations, and even other teams like marketing or sales, allowing all parts of the organization to align more closely with goals and projects.6. Start Documenting : Document everything (All your work done) which you are spreading across the process and infrastructure and specially the reports, RCA’s (Root cause Analysis), change management. This helps you to go back and see if all issues we faced can be automated in the next cycle or other ways to handle them smoothly without interrupting your production environment.7. Keep your eyes on cost burning: It has been experienced many a time that if we don’t keep an eye on cloud bills it will keep increasing and will tend to be proportional to the growth of your business till the time you don’t look for optimization. Always do an audit in 2 months and evaluate your cloud computation to optimize. Do some experiment with infra because you should not spend not more than 5  to 10 % of cost for cloud infra if you are completely dependent. Tools you can try : Reoptimize, Cloudyn, Orbitera etc.                                                                                 “If you are DevOps you should account the no’s.”8. Secure your infra : If your team follows certain compliances from day 1 then there is very less chance to compromise with your data and this can be easily enabled by providing a setup where you can verify your vulnerabilities. Before moving your build to the production team you may need to follow the standard at an early stage of development by using configured tools like: SonarQube, VeraCode, Codacy, CodeClimate etc.9. Tool Selection : Always select tools which all are compatible with rest of the toolchain you are planning to use. Why you should have to be so careful is because you have to capture each and every request capture. Once you are done with the tool selection, draft a tools metrics you are willing to capture or will be going to help you to debug. Start logging and monitoring them and have some clear definition for those logs so you can justify and determine that your processes are working as expected. Tools you can have a look : Nagios, Grafana, Pingdom, Monit, OpsGenie, Observium, Logstash etc.                                                                                                        Tool chain for DevOps process:                                                                             “If you are not monitoring,  you are not in the production”Conclusion:An organization that follows all the above best practices creates the right culture, which finally gets the ending it deserves i.e DevOps organization. "A good DevOps organization will free up developers to focus on doing what they do best: write software," says Rob Steward, Vice President of product development at Progress Software. "DevOps should take away the work and worry involved in deploying, securing and running the software once it is written."

DevOps & Automation- Advantages Of DevOps

Automation is the key to realizing the philosophy of DevOps and in ensuring that it delivers. The underlying building blocks of DevOps are to ensure that the engineering platform is in place to facilitate continuous delivery, integration, and improvement.  Consider the following processes that have traditionally been carried out manually- Creating development, testing and production infrastructure and configuring networks Harnessing security and data protection Setting up, configuring and deploying software Testing and validation of data – data generated from the application and about the usage of the application Supporting infrastructure and the applications running on it – maintenance, upgrades and transitions In a traditional development scenario, each new environment has to be created from scratch and include all of the above processes, making it a very tedious and lengthy process. However, in a DevOps environment, releases are more frequent and time for testing and quality assurance is therefore much shorter. Performing all these tasks manually therefore severely undermines the efficacy of the DevOps approach. However, it is not just about making DevOps possible, it also has its own advantages. Unexpected errors in production still occur in manual builds as it is difficult to exactly replicate each environment. This in turn, increases the risk of errors occurring in production after testing has been carried out on non-identical pre-production systems. In today’s software world, it is all about productizing and replicating solutions. A product needs to be customized and deployed at a new client site within a really short period of time. Once deployed, the operations support team must be able to support with issues, bug fixes and day-to-day activities in a smooth manner. Similarly, a product deployed for one business domain must easily be configured and utilized by another industry. Such is the flexibility expected from software today. What’s more, in the traditional development cycle, each member of the team has a local copy of the code. When a developer implements a new feature or fixes a bug locally, once complete, the new code is committed back to a central repository. But in a team of developers and system operators, more than one individual can be following this process at the same time, unintentionally breaking the code or affecting another developer’s code. The rule of thumb is that the greater the human intervention, the more testing that will be required. Pre-production or development environments become non-standard which makes processes like testing or releasing new software versions more difficult to repeat and more prone to error. In worst-case scenarios, developers are left to re-invent the wheel each time they need to make changes in response to new business demands. The advantage of DevOps By creating a more responsive development environment that is closely aligned to business requirements and which removes human error from the project lifecycle, DevOps enables organizations to:  Reduce the implementation time of new services from months to minutes  Increase productivity of business and IT teams  Save costs on maintenance and upgrades, and eliminate unnecessary capital expenditure  Standardize processes for easy replication and faster delivery  Improve quality, reliability and reusability of all system components  Increase the rate of success for digitalization strategies and transformation projects  Ensure that money invested in cloud infrastructure, analytics and data management are not wasted Since it focuses on delivering value much earlier in a project lifecycle, DevOps can be seen as an ideal approach to national and government IT projects, as well as massive scale projects for the private sector. It helps accelerate new services through continuous improvement and operational flexibility, providing innovative and cost-effective ways for delivering value through new ways of development and operations.

Top 7 Ways of Obtaining Business Benefits of DevOps

In any organization, finding a new way of working, often materializes through adopting DevOps, which provenly is the best approach towards the success of an organization. It is imperative that the team members step out of the silos and go for the team-work. One of the crucial facets of DevOps is- it creates an environment in which developers can work closely with the operations team and key stakeholders involved in the software delivery process, by a systematic breakdown of the traditional approach. It is obvious that any change in an organization results in the investment of time, money and expertise. Therefore, the leaders can evaluate the potentiality of DevOps in terms of the deliverables and the net gain, by changing their current approach towards project completion. Automation software vendor, Puppet published one report, illustrating the broad range of benefits from DevOps.Through a series of company-wide surveys, Puppet polled about the DevOps experience from 4,600 technology professionals. The response was overwhelming. By adopting DevOps, the organizations were deploying the existing softwares more rapidly and effectively, without the quality of the software being compromised. Listed below are some of the benefits of DevOps which brought significant changes in corporate performance- Faster Deployment: The ability to develop the newer systems more rapidly by taking inputs from the developers, teammates and key stakeholders, is undoubtedly a key benefit of the DevOps approach. In the traditional approach, the software is updated through irregular iterations. For example, a company wants to upgrade the software in every 12 months to pace up with the customers’ expectations and added improvements by the competitors. The root of the insecurity of the competitors lies in the fact that they innovated the latest version of the desired software immediately after its advent, which indicated that when the updated software will come to the market, the version in use will already be outdated. DevOps and Agile approaches enable companies to stay afloat in the fast-paced global market. This results in continuous and uniform deployment. Due to these approaches, the successful IT Organizations are deploying 200 times faster than the lower performers. Improved Recovery: In the digital age, IT failure in any form, is detrimental to the growth of the companies. If the system goes down during the peak hours, the customers are likely to face major inconveniences. The Puppet survey tells us that the failure rates are reduced due to DevOps, while recovery speeds are increased by nearly 24 times. This is possible because DevOps supports the small changes, which can be identified easily and can be rectified as fast as possible. Increased Scope of Values Delivery: DevOps adoption creates a continuous delivery environment. This results in the creation of favorable conditions, with a continuous focus on new changes and enhanced value creation via Digital Transformation. Lean and Flexible: DevOps supports the Digital Transformation processes like Lean and Flexible. The major projects are managed by splitting the work into smaller segments. DevOps practices help to improve data gathering and ability to respond quickly. Reduced Risk: Digital Transformations have risks attached to them. Updating the existing systems leads to problems like failing security and more error-prone changes. DevOps reduces such risks by adding security to the software delivery lifecycle. This results in saving time by addressing security issues. DevOps for all Reasons: Every organization has different requirements. Some may work on legacy systems, so they are using the software related to the same. Some may focus on education, so they are dealing with the educational software, and so on. The main advantage of DevOps is that, high performance can be achieved, regardless of any software. HR Matters: In an organization, HR matters both in terms of maintaining existing staffs and attracting new ones. It is found that the employees working in high valued teams, are likely to recommend their organizations to their friends. Before the DevOps practices, the businesses were taking much time, at times around 9 months to upgrade the software. This turned out to be a very problematic situation for the businesses. After implementing DevOps practices, upgrading the software is taking just 4 weeks. Clearly, DevOps has evolved in more than one way to yield myriads of business benefits in the burgeoning organisations.

5 Benefits Of Getting A Devops Foundation

DevOps is a popular term in the IT world today and is a combination of development and operations. Engineers from both the fields work together to offer clients what they’re looking for—from design and development to implementation and support. An Insight Into The World of DevOps DevOps was created out of ‘Agile’ software development where software solutions and requirements evolve from the collaboration of different cross-functional teams. Agile software development promotes evolutionary development, adaptive planning, continuous improvement, and early delivery and also promotes flexible and fast response to changes. DevOps and Agile are somewhat similar but differ in various aspects. Agile is nothing but a set of principles followed while developing software. DevOps takes into account into account the operational and functional aspect of development as well. Many developers consider DevOps to be an extension or subset of Agile. DevOps Training & Certification The popularity of DevOps has increased significantly since its inception and there is a huge demand for DevOps certified professionals in the industry. Number of institutes have come up that offer DevOps certification and solid training. There are three certifications related to DevOps—Foundation, Certified Agile Service Manager, and Certified Agile Process Owner. Here, we’ll look at the Foundation certification in detail and the benefits associated with it. Learning Objectives of DevOps Foundation The learning objectives include getting an understanding of the following: ● DevOps objectives and vocabulary related to it ● How DevOps benefits a business? ● Concept and practices in DevOps and its relation to Agile, ITSM (IT Service Management), and Lean ● Performance measures and results ● Culture, collaboration, and communication ● Key performance indicators and critical success factors ● Real-life results and examples Foundation is the introductory DevOps Certification and certified individuals are able to implement the practices and concepts of DevOps and improve workflow and communication in the organisation. DevOps Foundation certification is a great option for individuals involved in areas of service and product lifecycle. It is also useful for managers and employees working in IT firms and bolsters the designing and development processes. DevOps Foundation certification can also help developmental consultants and external and internal suppliers. Getting this certification renders a solid understanding of everything related to DevOps and makes you more desirable in the job market. Candidates need to have sound IT and service management knowledge and are required to complete a 16 hour instructor-led course from an institution offering DevOps courses. Let’s look at the benefits of earning this certification. Benefits of DevOps Certification Benefits of DevOps Foundation certification are immense and some of them include: 1. Better Job Opportunities DevOps is more or less a very new concept in the industry and more and more companies are deploying DevOps practices. There is a dearth of certified professionals who can bring in their DevOps expertise to organisations. A DevOps certification will expand your horizon as an IT professional and better job opportunities will come your way. 2. Improved Skills & Knowledge The DevOps ideology encourages a complete new way of thinking and decision-making. The business and technical benefits of DevOps are many and you learn how to implement them in your organization. You learn to work in a team consisting of cross-functional team members—QA, developers, operation engineers, and business analysts. 3. Increased Salary According to a recent survey, DevOps certified professionals are among the highest paid in the IT industry. The market demand is increasing rapidly with its increased implementation worldwide and this trend is not going to change any time soon. 4. Increased Production & Effectiveness With a DevOps certification, your productivity as an IT professional will increase. In a typical IT environment, a lot of time is wasted waiting for other people and other software. Everyone likes to be productive at work and the time you waste waiting is sure to cause frustration. With DevOps, you can get rid of this unsatisfying part of your job and spend the time adding more value to your company and your staff. 5. Benefit Your Organisation By earning a DevOps certification, you can offer your organisation loads of measurable benefits. DevOps ideology promotes increased collaboration and communication between the operation and development teams. The frequency for release code that goes into production is increased due to a shorter development cycle. What took 3-6 months before, will take only a few hours with DevOps implementation. Defect detection will also become easy. So, be among the first in your peer group to get a DevOps Foundation certification to climb up the career ladder rapidly. Make sure to choose an accredited training organisation.
