Introduction

IT organizations are relentlessly challenged time and again to deliver new software applications even faster thanks to the ever-evolving businessdynamics. Meanwhile, incumbent enterprises that once relied on their IT cores as a source of competitive advantage now expect greater availability (24x7), speed, resilience and security to achieve business agility and a formidable scale at a rapid pace. This leads to a surge in the demand for DevOps.

The era of traditional models has dulled the end users’ feeling ofexcitement and anticipation for every “full fat” new software release.Today is about designing short sprints, accept fail fast method, quick release and rapid scale. It’s about being more agile to fit in the modern business landscape.

DevOps: A Key Building Blockof Business Agility

DevOps is an arsenal of the most modern tools and technologies thatencouragingly support the process of agile software development. Thissoftware delivery approach is used by the operations and development team to seamlessly develop, test, deploy and assess applications ensuring speed, quality, resilience and governance.

DevOps is not just a methodology but an intentional mindset that needs to be woven into the values and cultural fabric of an organization. Besides, its adoption is unavoidable to keep your stride at par with high-velocity business rivals.

AGILE BUSINESSES USING DEVOPS

At its core, DevOps is a software deliveryapproach that brings people, process, and technology together through communication and collaboration. It can foster a continuous process of the application managementlifecycle with the shortest possible turnaround time to deliver high business value to the organization and its customers.

While most IT leaders think DevOps is an antidote to the organization’sine�ciency, it’s ironic that barriers to its adoption even in willing organizations exist.

The biggest challenge toimplementing DevOps arises when

you set out to Modernize LegacyApplication Infrastructure.

Infrastructure management is a fundamental element for any organization striving to adopt a DevOps approach.

Before charting your DevOps journey, it is imperative to understand why previous ways of working are obsolete.

Unfortunately, majority of companies face a challenge in maintaining existingenterprise applications due to critical IT infrastructure issues. Whether that means adopting agile principles for software applications, hardware and databaseintegration, enhancing customer digital experience or shifting to newer technologies such as microservices, cloud computing or serverless computing for deliveringsoftware.

That’s why end-to-end modernization of application infrastructure promises to address the most immediate pain points and the subsequent issues as they occur.

Old Not Gold: Challenges of theLegacy Application Infrastructure

As digital disruptions impose greater demands on IT systems andorganizations, companies must consider an end-to-end approachfor upgrading and managing business technologies.

- McKinsey & Company

Until recently, application architectures were single, unbreakable monolithic in design and operation. Although consisting of many services, it still operated as a single unit presenting several operational challenges:

Competitive pressure and growing functional requirements can no longer besupported by the layered stack of legacy systems. However, these challenges canbe avoided as the DevOps program gears up.

BRITTLENESSIf any single part of the

application fails, then the entire application fails.

RISKOperated as a single unit in the form

of a package, everything fails together causing system-level outages.

TIGHTLY COUPLEDTightly coupled integrated networks

hinders the process of upgrading components of an application

individually.

DEPENDENCIESDevelopment and operations teams

work in silos to develop, test and deploy applications, increasing time

and poor productivity

Application Modernization means refactoring or reengineering of existing business systems to better respond to business needs, cater

to market demand and for data-driven decision making.

Four Ways to Swiftly ModernizeEnterprise Application Architecture

For most established players, reorienting IT operations around a two-speed IT architecture - which features stable, transaction- oriented systems on the back end and fast-changing, customer- facing applications on the front end —is a prerequisite for implementing both agile and DevOps approaches.

Oliver Bossert, Chris Ip, and Jürgen Laartz, “A two-speed IT architecture for the digital enterprise”

IT’S TIME TO REORIENT APPLICATIONINFRASTRUCTURE

Companies who are early adopters of digital technologies have revolutionized the fundamental approach of building and managing application infrastructure. For instance, a web-native company like Netflix has created a cloud-based ITinfrastructure. This allows the operational team to focus on continuousmanagement of hundreds of microservices hosted in the cloud- each servicemanaged by a dedicated DevOps team to rapidly design, integrate, test, deliver, and monitor software changes.

Modernizing makes sense if done correctly. Companies that cannot rely on theoverextended complex legacy applications are looking for ways to move forward without disrupting the established business processes.

Persisting legacy infrastructure can bring stability issues, lack of support and fear of leaving behind the swiftly advancing competition. Microservices enable loosely coupled structuring of an application – allow breaking of a large application into distinct domains. Each component or service within the system can be managed, scaled, and monitored individually. Establishing new microservice architecture can remove deadlocks to faster development and quicker innovation.

Traditionally, manual deployment of applications is time-consuming and causes a slow release cycle. Infrastructure as code is an approach to manage and provision IT infrastructure for continuous deployment using built-in DevOps capabilities or integrate with Jenkins. It can configure and deploy server, database, network and software quickly – fostering speed, reliability and consistency.

2. MANUAL TO AUTOMATED DEPLOYMENTS

Vertical scaling of data resides on a single node often limited to the capacity of a single machine. It can be scaled spreading the load between the CPU and RAM or adding more RAM or storage to your machine. However, beyond the capacity, it can lead to downtime. While horizontal scaling is all about adding more servers to the cluster of applications to spread the load on separate machines.

3. VERTICAL TO HORIZONTAL SCALING

HORIZONTAL SCALING(Add more instances)

VERTICAL SCALING(Increase size of instance

Modern applications consist of di�erent technology stacks and architectures, from n-tier to microservices and everything in between. Regardless of the application architecture, container technology such as Docker container allow portability of code across multiple environments with the least programming needs. It enables running an application inside the container; eliminating the interdependencies to rapidly scale independently and e�ciently.

8 Reasons Why Modern DevOpsis Better than Traditional IT

Understanding the di�erences between Traditional IT and Modern DevOps

PAGE 13


With traditional IT approaches, enterprises may experience the complexity due to disparity between the Developers and Operations team. Such challenges have a greater impact on the e�ciency and performance of the organization. Key synopsis on the eight key di�erences observed when DevOps organization as compared to traditional IT.

Planning & Organization

01

TRADITIONAL IT DEVOPSVS

Large Batch Size: Involves aninherently complex waterfall method where huge code is bundled into a release, leading to slow release cycles.

Micro Batch Size: DevOps believes in small batch sizes to perform more frequent releases causing minimal impact and quick execution.

02Organization Work in Silos: Disparate systems, development and operationsteamwork in siloes on di�erent areas of the applications.

Dedicated Cross-functional Teams: Consists of developers, testers, business analysts, and operators, who focus on only one application to achieve a common goal and encourages the “shift left” thinking.

03

Centralized Scheduling: The task of scheduling falls on the shoulder of one individual for all employees in the organization. However, in some cases, it becomes a bottleneck leading to an increase in data anomalies and a lack of visibility with each unit.

Decentralized Scheduling: In a DevOps organization scheduling is carried out by a collaborative team that makes scheduling simpler to operate.

PAGE 14


Performance & Culture

01


High-Risk Software Release: The process is tightly coupled and requires participation from all parts of the organization.

Non-Event Software Release: The loosely coupled process reduces risk by integrating code continuously, ensuring all environments are operating in synchronization.

02

Disseminated Information: Information is generated by specialists (e.g.operations team), bundled together with other data into a massive report, which is shared with other teammembers but poorly consumed, and rarely used to take any actions.

Actionable Information: Information is collected and shared by thecollaborative team which eliminates the time lag of creating lengthy reports resulting in faster feedback time.

03Do Not Fail: Fundamentally a risk-averse organization focuses on preventing failure and not harming the business.

Fail Fast: A DevOps organization prefers to fail small, fail early, and recover fast.

Measure

01


Focus on Cost and Capacity:Development and operations are solely based on how much can it get done (capacity) for the least amount of cost.

Focus on Cost, Capacity and Flow: In DevOps organization, Flow is the added aspect to gain visibility on end-to-end CI/CD operations that help to identify errors, estimate true productive time, measure quality, and focus on activities that add maximum value.

02Hando� Deadline: Specialists focus on completing their job and handing o� due to lack of coordination andcollaboration resulting in quality loss.

Ready to Deploy: Every member of the cross-functional team is accountable for bringing quality software to the market.

Gitflow is a collaborative branching model that normally follows the agile process where the requirement is broken down in the form of epics, use cases and user stories.

It also enables the team to create branches (Feature, Development, Test and Release) from a branch called “Master.” Master allows the branches to operate parallel to each other so the distributed team can work e�ciently where each team member focuses on an individual feature branch. This way each member gets to cherry-pick features for development, while encouraging frequent commits and automated testing.

Once the development is committed, it is pushed to the feature branch andsubsequently, a peer review is generated. Using the multi-branch pipeline feature of Jenkins, an automated pipeline gets triggered, where we define the entire set of jobs which includes code compilation, creating Docker images, running unit tests and sonar scanning for any known vulnerabilities in the code.

Once the pipeline is successful, the Git gets notified for PR review. Here we insist the team leads verify the business logic written and once approved, the feature branch is merged with the development branch, which in turn triggers another Jenkinspipeline to deploy the dockers on the dev environment and run di�erent types of automated testing.

Based on the result, the application gets deployed on the Test environment or the pipeline will fail and reject the build.

The subsequent movement of builds from Test to staging and then to productionis condition-driven which is based on the test result. In the entire process, oneimportant aspect to note is the integrity of the builds are maintained, avoiding“work on my machine” philosophy, which in turn ensures the optimum quality of theapplication by letting the app pass through the various stages of validations.

Using Integrated DevOps Toolchainto Deliver Scalable Customer-CentricInnovation with Speed

As companies are rushing to implement DevOps, the entire software development life cycle (SDLC) is going through a paradigm shift. In the DevOps environment, integrating toolchain is crucial to maintain a continuous feedback look withinformation moving back and forth and logging everything in between as it should reflect and adhere to a common set of business objectives.
