Application Modernization

#Day1:Introduction To Application Modernization

A simple approach to modernizing or update the outdated application be it in terms of security, automation, experience, etc.

Why we should modernize legacy applications?

Among the organizations, its common feature is also known as a Digital Transformation Strategy, focusing mainly on the following:

• Investment aspect to update, renew or sometimes refresh the software, thus increasing in the infrastructure, tools, languages and either technology process as well.
• Results in decreasing CAPEX(Captial Expenditure) or OPEX(Operational Expenditure) i.e resources needed to run an application.

What are the types of application architecture?

• Monolithic Architecture(Tightly Coupled, Single Tier application)
• SOA(Service Oriented Architecture, similar to API, used for providing services to other components by application components)
• Microservices(Loosely Coupled)

What are the patterns in an Application Modernization?

• Rehost(Lift and Shift the existing application from On-Premises Server to New Infrastructure, say public cloud platform)
• *Replatform(Act as a middleman between rehost and refactor)
• Refactor(Restructuring/Rearchitecting)

* Highly Preferred

Technologies for Application Modernization

• Cloud Computing(IaaS,PaaS,SaaS)
• Microservices
• Containers
• Orchestration and Automation

(Orchestration is a process of running, starting, stopping, restarting the containers)

Benefits of Application Modernization

• Cost-Effective
• Better Security
• Automation
• Meeting Compliances
• New Revenue Streams
