Waterfall vs Agile Model

Uncategorized /

Initially, it is very important for us to know the basic meaning of the terms Waterfall and Agile, before exploring the differences between them. In a simple way, we describe, Agile means ‘able to move quickly and easily’ and hence that is what it means when it comes to the Agile development methodology. | Waterfall vs Agile The waterfall model is a linear sequential model in which the progress flows majorly in one direction downwards through the phases of requirement gathering, analysis, design, development, testing, deployment, and maintenance. The finished product is delivered once to the customer at the end of the deployment phase. This is the oldest model for software development. Agile is a method of project management that is represented by splitting of tasks into shorter segments of work with frequent reviews and adaptation of plans. Waterfall vs Agile This same example applies to the concept of project management when it comes to the waterfall model. This is a method of project management, that is represented by serial stages and a fixed plan of work. In the Agile approach, the software development, the whole project is broken down into small manageable Segments or units. Agile is based on the iterative development model where the requirements and the solutions grow through a collective effort of self-disciplined & the cross-functional teams and their customers/stakeholders. There are multiple iterations (often called Sprints) of adaptive planning, design, development, testing (these phases also overlap with each other in the sprint) and delivery. At the end of each sprint, an MVP (Minimum Viable Product) is delivered. MVP (Minimum Viable Product) is agreed to a subset of the product features. Waterfall methodology is a model, where each stage of the product’s life cycle occurs in a sequence. The progress of the project flows gradually downwards, which resembles a waterfall. Agile methodology is a model that follows a linear, sequential, and iterative approach. This model believes in a one-time massive whole delivery. This model believes in multiple small chunks (unit) of delivery at defined time intervals. The product is delivered at the end of the SDLC. An MVP (Minimum Viable Product) is delivered at the end of each sprint. It’s a traditional and old-fashioned approach. It’s a new and modern approach. One single cycle and single release. The repetitive number of iterations and multiple releases. It divides the software development lifecycle into different phases. It divides the software development lifecycle (SDLC) into sprints. This project has gotten so big, I’m not sure I’ll be able to deliver it! It’s so much better delivering this project in bite-size sections the process is treated as one, a single project which is further divided into different phases. The process is divided into multiple projects and each project has its own iteration of different stages. Structured and rigid model. This methodology is known for its flexibility. Long-term planning scale. Short term planning scale. A long-distance exists between the customer and the developer. A short distance exists between the developer and the customer. Long time between specification and implementation. The short time between specification and implementation. Takes a long time to discover problems. Problems are discovered quickly. High project schedule risk. Low project schedule risk. Less ability to respond quickly to change. High ability to respond quickly to change. The testing phase occurs only after the completion of the development phase. Testing is generally performed in parallel with the development to ensure quality continuously. The customer is involved only at the requirement gathering phase and after, there is no involvement of the customer.

Jenkins Basics by TeamITServe

Uncategorized /

Kohsuke Kawaguchi, who is a Java developer, working at SUN Microsystems, was tired of building the code and fixing errors repetitively. In 2004, he created an automation server called Hudson that automates build and test task. | Jenkins Basics In 2011, Oracle who owned Sun Microsystems had a dispute with Hudson open-source community, so they forked Hudson and renamed it as Jenkins. Both Hudson and Jenkins continued to operate independently. But in short span of time, Jenkins acquired a lot of contributors and projects while Hudson remained with only 32 projects. Then with time, Jenkins became more popular, and Hudson is not maintained anymore. What is Continuous Integration? Continuous Integration (CI) is a development practice in which the developers are needs to commit changes to the source code in a shared repository at regular intervals. Every commit made in the repository is then built. This allows the development teams to detect the problems early. Continuous integration requires the developers to have regular builds. The general practice is that whenever a code commit occurs, a build should be triggered. Continuous Integration with Jenkins Let’s consider a scenario where the complete source code of the application was built and then deployed on test server for testing. It sounds like a perfect way to develop software, but this process has many problems. The whole process was manual which increases the threat of frequent failure. contact the TeamITServe team today for help.

DevOps Trends in 2021 || TeamITServe

DevOps /

DevOps (the concept) was introduced in 2008 by Andrew Clay and Patrick Debois to act as a bridge between developers and operations and eliminate dysfunction. We are now in the second decade of DevOps and, it’s no longer just about the developer and operations team but also about the customer. DevOps has come a long way since its inception and is going strong as more and more organizations are integrating DevOps for efficient development and delivery cycles. | DevOps Trends The Future of DevOps Security was already a concern in the digital world, Covid 19, and work from home has fuelled this concern to new levels. As more and more employees work from home, security is necessary at every layer of the business process. Businesses are adopting DevSecOps and will continue to do so in the future. More than 4 billion people are using the internet today and, Covid 19 has accelerated the growth of internet expansion and digital adoption. Users generate a lot of data for businesses to process. AI and ML technologies help organizations deal with the available quantity data in a fast and cost-effective manner and scale. The use of these technologies will only increase with time. Kubernetes is a popular open-source platform for container orchestration and helps in streamlining the entire software development cycle (building, testing, deployment). Kubernetes eliminates manual tasks and helps enterprises meet growing and changing consumer demands. Bugs are a nightmare for the security of any application. The Shift-left approach encourages finding and fixing these issues in the early stages of the development cycle as it is the cheapest to do so at that moment. By giving more importance to developers and security, code rollout has become relatively bug-free and cheap, and the situation will continue to improve in the future.

The DevOps Lifecycle | Basics on TeamITServe

DevOps /

The traditional software/application development process is very complex, with the development and operations teams working in siloes. The process is slow and error-prone. DevOps facilitates the modernization of the traditional development process by allowing development and operations to collaborate, from the development phase to the delivery phase of the software development cycle. DevOps is an efficient, time-saving, and relatively error-free process that ensures better software quality and high consumer satisfaction, a win-win for organizations. | DevOps Lifecycle The DevOps lifecycle has seven phases to ensure an efficient, automated, fast, and error-free development process. The different phases are as follows:  Every project has a vision, and the first phase of the DevOps lifecycle is laying the groundwork for the application based on that vision. Planning is completed based on the project. Once plans are in place, coding initiates as a part of the first phase. Commonly used programming languages for coding are Python, C/C++, JavaScript. Git is the most used Source Code Management (SCM) tool for setting up a centralized management structure for the project. Coding as a process has to be performed repeatedly in software development to ensure stable and bug-free functionality. In this phase, the developer integrates the updated code with the existing one. It helps to add new features to the software and fix bugs. This process ensures bug removal in the early stages, and the end-user gets to use a stable product. Jenkins is a popular DevOps tool used for updating the code and generating .exe format builds. As the name suggests, the developed code is tested continuously for bugs and glitches in this phase. One of the most common tools used for continuous and automated testing is Docker containers. Manual testing is a time-consuming and lengthy process. The automatic process allows the developer to test code multiple times in short periods, which is not possible with manual testing. It ensures that the development process is quick and the software is bug-free. Some popular DevOps tools used for automated testing are TestNG, Selenium and Junit. Bugs and glitches can completely ruin the software experience for the end-user. Enterprises need to keep their software and services bug-free and updated to sustain. In this phase, complete monitoring is done majorly by the operations team to check the software application and iron out bugs or any other recurring issues using tools like Sensu, ELK Stack, NewRelic, etc. This process results in a product that is more reliable and efficient for the customer. Feedback sharing is one of the biggest reasons which make DevOps so effective. Traditionally developers and the operations have worked in siloes resulting in a complex operating structure. DevOps encourages the two groups to collaborate, share feedback freely and instantly for a quick and efficient development cycle, increasing the overall quality of the code and the subsequent application. Users can also provide feedback which helps the developers push out relevant software updates. Consistency is the key with DevOps. Configuration management tools like Chef, Puppet, and Ansible are the most used in this DevOps lifecycle phase for continuously deploying the new code. Containerization helps to establish consistency across the various stages of the development, leaving low chances of failures and helping to scale up and down instances with ease.  This phase is the last in the DevOps lifecycle and probably the easiest. It helps in creating an automated development cycle for the software. Enterprises can deliver products and updates to the market quickly, ensuring high code quality and customer satisfaction.

What is GitHub? A Beginner’s Guide on TeamITServe

Uncategorized /

Git is a distributed SCM (source code management tool) and is one of the most used DevOps tools. There are two types of version control systems centralized and distributed. Git is a distributed version control system. Users can save different versions of their source code and return to previous builds whenever necessary. Currently, the two best online Git repo hosting services are GitHub and Bitbucket. GitHub Git is a popular tool for collaboration among developers and, GitHub is an open-source platform based on the cloud for the developers using Git. GitHub has a community of around 30 million developers and, Microsoft acquired it for $7.5B in 2018. Individuals can work together on projects using GitHub and, since Git is a distributed version control system, each individual gets a separate file to work. People can open issues on GitHub to report errors and, the concerned developer can work on it seamlessly by creating an alternative source code. GitHub makes the process of code creation, sharing, and bug fixing effortless and seamless.  One advantage of using GitHub is the interface. Git requires a level of technical knowledge to operate but, GitHub is so user-friendly that even novice users can work it with ease. Some people also use it to complete other tasks like writing books because of how easily multiple people can work on the same project. GitHub as a platform has many paid services and business plans making it easier for organizations to manage employees, projects, and security. GitHub is fast, reliable, stable, and user-friendly. GitHub has an extensive library of guides and articles all related to Git. GitHub has made collaboration extremely easy for coders and organizations. Even as a platform for backing up projects, GitHub is right there competing with the best platforms. GitHub continues to evolve. With an open-source ecosystem, a large number of active users, and a very user-friendly interface GitHub is probably the best Git-based platform. Want to implement DevOps?

How DevOps Contributes to a Business

DevOps /

DevOps makes the development cycle faster. Automation tools like Ansible, Jenkins, maven, puppet help reduce the latency and friction in the development cycle. The exchange of complaints and suggestions happens almost instantly. Operations can effectively guide developers for what is needed and, developers can be part of the deployment process. This collaboration not only ensures a free flow of information but also reduces conflicts. The result is more polished software and faster updates. DevOps ultimately results in low cost of production and time consumption. The outcomes achieved with the correct implementation of DevOps are: Fully Automated Deployment: DevOps-centric operations include automated deployments. Having automated deployment from start to finish increases an organization’s efficiency and reduces errors. Manual deployment can be slow and inconsistent due to human error but in the case of automated deployments, reverting to the previous builds is easy that saves both time and effort in situations of error. Frequent and Rapid Release Cycles: With DevOps, the release cycle for software and services is fast and efficient. We are living in a competitive world where the release cycle can make or break the business. DevOps helps to release new features and bug fixes rapidly and frequently. Clutter-Free Operations: DevOps is all about integration and automation. With the right mindset and tools, any organization can transform into an efficient machine releasing quality software and services with fast and reliable support. DevOps thus results in lower operating costs and higher client satisfaction. Continuous Feedback Loop: One reason DevOps is so effective as it creates an environment of exchanging feedback. Feedbacks are necessary for an organization to operate. Since the developer and operations work together, feedback sharing is quick, resulting in a fast and efficient development cycle.  Development and Operations Groups Work Together: DevOps helps bridge the gap between developers and operations. This partnership thus created transforms the organization upside down. With DevOps, development is fast, operations efficient and, the flow of suggestions is smooth. Clear Establishment of Goals and Objectives: DevOps simplifies operations. It helps organizations establish clear goals and objectives. When goals are clear, organizations can sustain the market competition, give clients the best experience possible and score high profits. An organization with clear objectives is always the better one. Want to implement DevOps? Consult the TeamITServe team today for help.

Most Used DevOps Tools

DevOps /

DevOps Tools | DevOps is a set of practices that combines software development (Dev) and IT operations (Ops). DevOps is an environment where developer and operations work together throughout the entire service lifecycle, from designing and development to product support. It aims to shorten the systems development life cycle and provide continuous delivery with high software quality. DevOps has become essential for growth and survival, but protecting the software delivery and deployment pipeline has become more critical than ever before. DevOps as now become more important than ever before. Hundreds of tools are available out there for DevOps. Some of the most frequent tools in the world are: Kubernetes: It is necessary to use an orchestration platform (the management of applications built using containers) to scale and manage your containers. Kubernetes is a popular open-source platform for container orchestration. Docker: Docker is an open-source software development program that helps developers build portable software containers for faster application development and deployment. Docker uses the host’s OS kernel instead of requiring a special one to run the application. This results in both boosted performance and the application is lightweight. Docker is beneficial for both developers and operations. It helps developers code with ease without worrying about the machine on which it will ultimately run. As for the operations team, Docker gives them a lot of flexibility due to its small footprint and lower costs. Jenkins: Jenkins is an open-source CI/CD server that allows users to automate different parts of their delivery pipeline. The main reason for its popularity is the massive plugin ecosystem. With Jenkins, you can iterate and deploy new code as quickly as possible. It also allows you to measure the success of each step of your pipeline. Git: Git is a distributed SCM (source code management tool) and is one of the most used DevOps tools. Git allows you to track the progress of your development work. Users can save different versions of their source code and return to previous builds when necessary. To integrate Git with DevOps workflow, repositories should be hosted where the team members can push their work. Currently, the two best online Git repo hosting services are GitHub and Bitbucket. Bamboo: Bamboo is also a CI/CD server similar to Jenkins and developed by Atlassian. Both the tools allow users to automate their delivery pipeline, from builds to deployment. Bamboo saves a lot of configuration time and comes with an intuitive UI, auto-completion, and many other handy features. Consult the TeamITServe team today for DevOps consulting.

Reducing the Cloud Computing Expenditure

Cloud /

Cloud Computing Cost Reduction | Cloud Computing has revolutionized the way businesses operate. Complex tasks are now easier to perform, and data processing is more efficient with Cloud Computing. In 2021, Cloud integration has almost become a necessity to survive in this competitive environment. Maintaining cloud services can be a tedious task. Operating on the Cloud: Cloud Computing can significantly decrease the operating cost for businesses. For example, imagine taking an Uber. It will always be cheaper than buying a car (no need to pay taxes, maintenance charges involved with owning a car). Same way, operating on Cloud means there is no need to buy physical systems. You can use what you want when you want and pay only for what you use. Due to these cost savings, more than 40% of the businesses have ditched their legacy systems for the Cloud. Cloud Computing is cost-saving but, a coin has two sides. Unused resources generate unnecessary costs resulting in decreased profit margins, in some case even losses. Here are some crucial tips that can help you optimize and lower your Cloud expenditure: Precise Asset Management: Take charge of the management. Recognize the need of the business. Extra resources add up to the expenses. When operating on Cloud, make sure that the resources match the requirements.  As per need: Not all processes need high-end servers to execute. Businesses can split their usage across offline and online mediums to bring down cloud expenses. On the Cloud, workloads can be assigned to specific systems best suited for their execution. Also, not all businesses need servers to operate. In that case, pay for the required functions. It can save enterprises a lot of money, resulting in higher profit margins. Pay-per-use: One of the most primary features of the Cloud includes the pay-per-use, where businesses can pay only for those resources that their website has used. Hence, offering a very value for money experience. If utilized efficiently, Cloud Computing can do wonders for businesses. So why wait? Get started with Cloud Computing today.
