What is DevOps ?
It is the combination of cultural philosophies, practices and tools. The aim is to increase an organization’s ability to deliver applications and services at high velocity. It can evolve and improve products at a faster pace than using traditional software development and infrastructure management processes. This speed allows you to serve your customers in a better way and have a high competency in the global market.
Challenges for Traditional Companies
Business applications and associated development processes are slow to respond to competition.
There is an increasing need to build customer community and brand loyalty through a variety of channels.
The IT team is overstretched in order to support the new products development.
Innovation fails to keep up with competition and to create customer value quickly.
The First Step – Inception
It starts with essential tools familiarisation. Workshops and trials will be arranged with customer. Then, a prototype will be built on business case with Minimum Viable Product (MVP). Finally, presentation will be made for next phase commitment.
The Second Step – Elaboration
It starts with defining the MVP architecture baseline with microservices. Then, architecture workshops with customer will be arranged to identify business services and the supporting architecture. The most important part is to prepare the project plan of resource, budget and timeline. Finally, presentation will be made for full construction commitment.
The Third Step – Construction
It starts with the introduction of a DevOps team structure with customer members. Enforcement will be made for continuous integration and continuous delivery (CI/CD) processes with related toolchain. Then, we will set up the related on-premises/ cloud environments and construct the MVP iteratively and incrementally. Finally, regular review of product readiness, resource capability and processes will be done.
The Fourth Step – Transition
It starts with the review of DevOps roles in team and their maturity. CI/CD processes will therefore be reinforced. We will consolidate the customer’s architecture, development and operation skills. The most crucial part is to have the cost and performance monitoring, control and reporting. Finally, we will provide continuous support through mentorship and managed services.
Benefits of DevOps
DevOps allows you to innovate for customers faster, adapt to changing markets better, grow more efficient. Microservices and continuous delivery enables ownership of services and release of update.
You can increase the frequency and pace of releases, and thus innovate and improve product faster. Continuous integration and continuous delivery auotmate software release process.
DevOps ensures the high quality of application updates and infrastructure changes. Continuous integration and continuous delivery ensures change is functional and safe. Monitoring and logging help you to stay informed of performance in real-time.
You can operate and manage your infrastructure and development processes at scale. Automation and consistency can manage complex systems efficiently with reduced risk.
DevOps allows developers and operation teams to collaborate closely, share responsibilities, combine workflows. It can further reduce inefficiencies and save time.
You can retain control and preserve compliance without sacrificing security. It allows you to use automated compliance policies, fine-grained controls, configuation management techniques.
DevOps Best Practices
Continuous Integration and Continuous Delivery
It is a software development practice that developers regularly merge code changes into central repository. Code changes are automatically built, tested and prepared for the release to production. It allows you to find and address bugs quicker, improve software quality, and reduce time to validate and release new software updates.
It is a logical packaging mechanism that allows applications to be deployed easily and consistently, no matter of whether the environment is private, public, hybrid or multi-cloud. Containers can provide a consistent environment which can create an isolated environment from other applications. Multiple containers can be deployed as one or more clusters.
It is a design approach with a single application as set of small services. Each service can run in its own process and communicate with other services through well-defined HTTP-based application programming interface (API). Microservices can be written by different frameworks or program languages, and can be deployed independently, as a single or group of service(s).
