Do you have an immediate need to quickly create digital services, but have longer term goals of simplyfying your legacy architecture or expanding your Cloud strategy?

Touted by analysts like Gartner and Forrester and used by organizations like Amazon, Netflix, Nike, and eBay, microservices are now a critical part of many enterprise cloud and digital strategies.

What Is a Microservice and a Microservice Architecture?

Microservice

A Microservice is a small, self contained piece of code thar executes a business function. It has a clear interface, and private data. Microservices can be written in many different programming languages and is one component in a service-oriented architecture. A microservice is decoupled and easily deployable insde a container into any environment.

Microservice Architecture

A microservice architecture is a set of loosely coupled microservices that implement a larger set of business functions. Microservice architectures are the defacto standard for developing cloud-based and cloud-native applications. The term used for this type of solution is cloud microservices.

Microservice Deployment

Microservices are easy to continuously integrate, deploy and test - plus software teams can work on each one independent from another. Microservices support continous delivery and service discovery in environments from serverless cloud computing to data centers.

Features and Benefits

Feature	Business Benefits	IT Benefits
Modularity	Build new products and offerings at a fraction of the time and cost	Reduce interdependence so applications are easier to develop, test, and update
Small, independent teams	Transform IT from business anchor into engine	Enable small teams to develop, scale and deploy services independently
Scaling	Efficient growth of services	Build new products and offerings at a fraction of the time and cost
Easier migration	Reduce time and cost associated with moving away from legacy systems	Accelerate future projects since APIs are microservices
Modern Development Paradigms	Quickly respond to ever changing market needs	Enable agile and DevOps software development practices
Global API	Deliver a unified user experience regardless of device, channel, or location	Enable organizations to develop a global strategy
Load Balancer	No longer waits for web services to return results	Don't overload one system and support a modern technology stack
Flexibility	Easier to manage your enterprise applications	Support for different programming languages

How to Best Use Microservices to Modernize Your Legacy System

The architectural style you choose can greatly impact your development, innovation, and business capabilities.

Compared to a monolithic architecture representing an entire system, microservices are faster to build, test, deploy, and update. Now, different parts of your development team can work concurrently on your products, in an agile manner, and deliver value to your customers immediately.

The key to digital transformation success is finding ways to access the mission-critical data stored inside data management platforms on legacy systems. Microservices, with APIs, make complex development easier. Microservice APIs also are easily accessed through an API gateway.

Microservices make testing easier because each unit is a self-contained individual service. You only nedd to test the ones that change. Each microservice is a small, separately loadable entity so deployment is simpler.

Why Aren't Companies Building Microservice Architectures for Legacy Systems on Their Own?

	Build Your Own	Use OpenLegacy
Creation	Complex There are complicated inter-relations between elements in a monolithic application	Easy Automatic generation of the microservice and API
Metadata parsing	Complex Need legacy systems experts to help due to complex application software architecture	Easy Anyone can use our pre-built legacy system specific connectors
Deployment	Moderate Need to add in wrappers for open source tools like Docker and Kubernetes.	Easy Pick from a variety of options and OpenLegacy does the rest

8 Reasons to Choose OpenLegacy

One Tool. One Step

Create a microservice and an API automatically. OpenLegacy's platform creates APIs contained within microservices, with a built-in connection to the legacy systems. In one step, create a legacy API and expose business processes. One tool, one step, and a giant leap for your organization.

No Middleware to Mess With

OpenLegacy's architecture does not require any middleware such as ESB and MQ, shortening the development and maintenance cycle and leading to significant cost savings. The entire application also executes faster without middleware and ends the reliance on additional 3rd party software.

Automatically Create Microservices

Automatically generate a microservice as a self-contained standard Java component. It features a standard interface which deals with a small problem domain and has an SDK, which refers back to a business process or data on the legacy applications.

Remove the Chains and be Free at Last

With decoupled microservices, you can launch the digital services you need, while making it easy to migrate off your legacy system in the future because the microservice is a defined interface that is easy to leverage.

No Modifications to Legacy Systems

OpenLegacy generates standard, lightweight code for microservices, and does not require modifications to the backend applications. In this case, we like being called a "lightweight."

Avoid Decentralized Application Monoliths

Our approach is quite different than " Integration microservices" offered by other vendors, where you end up with a "decentralized monolith" and microservices are depend on each other. Who needs that?

Decouple and Standardize

OpenLegacy provides an automated and standard way of functionally-decoupling a monolithic core application by creating a microservices architecture without changing the core application.

Oh, Plus Stunning Performance

Since we avoid complex layers of architecture, our microservices are extremenly fast. In fact, one of the largest banks in the world reported transaction reponse time improved by 70X.
