What Is A Microservice

microservice example

The general definition of microservices is a style of architecting applications as independent services, each of which serves a particular function for the business.

The pursuit of a digitized, data-centric enterprise has transformed IT teams globally. A part of the paradigm change is advancement in technology that shifted the requirements of IT departments.

Modern IT department Requirements:

– Encourage innovative thinking within their department

– Generate business applications that are always available

– Accommodate business users who want new ways to process data

These rigorous demands are almost impossible to meet, therefore a new class of business automation tools has been developed.

How IT Is Preparing For Microservices

Technological advancements place a demand on the enterprise in cost, execution, and adoption. Today’s enterprise is riddled with diverse and complicated problems that require innovation and disruption to resolve. Recently, the trend towards enterprise innovation has shifted towards business automation. A new practice that requires the agility and alignment of an IT department to succeed.

IT Agility 

For an IT department to become agile, it depends on the response of the enterprise to new business needs and desires of customers. However, the response of the enterprise is more than just recognizing a new requirement or desire, it is about being responsive in real time with new applications.

IT Alignment 

New business automation is better for the alignment of the IT department. This is because IT leaders are replacing C suite executives in leading efforts to create new applications that deliver a better UX experience.

IT leader concerns:

– reliability

– availability

– security

Business automation tools enable business users to design applications in secure and efficient ways.

The proliferation of this trend is seeing IT departments invest in ways to shift from monolithic applications to developing apps that are interchangeable with the rest of the organization’s infrastructure.

This practice began the rise of microservices in the enterprise.

Microservice Features

– Microservice is a singular process independent of one another

– Together microservices build a process

– The right microservice is a complete program that could run on its own

– Together microservices create an entire user experience

– For microservices, IT departments write components that do something and solve a problem

– Microservice processes are complementary yet independent

Microservice Vs. Client Service Microservice

The transition from monolithic services to microservices is based on trying to solve problems for a customer. Microservices have varying working definitions. One is a microservices architecture and the other is a client service microservice. While both microservices have general commonalities and are used as a solution to customer problems they differ in some ways. The former typically exists on the cloud and the latter is typically installed on a client interface.

Microservice Architecture

Components Of Microservice

Services

A microservice can be broken down into numerous component services. This is due to each service being independent; it should be able to be deployed, improved, and redeployed independently without compromising the integrity of the application. This gives the developers the flexibility to change one or more services without having to change the entire application.

Decentralized

By definition, microservices include a variety of technologies and platforms making traditional methods of centralized governance obsolete. The lack of reliance on centralized governance also makes microservices favor decentralized data management. While monolithic architecture uses a single database across different applications, in a microservice application, each service pulls from its unique database.

Scalable 

The essence of microservice architecture is taking one process and orchestrating it into a loose framework. A good example is a LEGO construction kit, which is a collection of blocks that can work together or stand-alone. Each component is doing its part for business goals. These parts contribute to a whole and together form a service. The services are joined in an API (application program interface) that regulates the interaction between system components. The independence of each service ensures its simplicity in development and maintenance as a standalone component. As a result, IT departments that use microservices for a system ensure its agility and scalability.

Client Service Microservice Architecture

Another microservice is client service microservice that typically exists on a client user interface. It is an orchestration of putting together “puzzle pieces” to solve an unknown problem for a client.

For example, the Content Analytics Platform (CAP) from Scion Analytics uses textual information as input to solve problems for a client. For enterprises, increasing client needs led to the refinement of the customer engagement process.

Components Of Client Service Microservice 

For Scion Analytics, it generated an innovation cycle with phases of:

Discovery And Planning 

The client and Scion Analytics team choose the best value use case from past experience and select and inform critical team members. They hold meetings to define input, output, and goals. Together, they identify measurable goals for the project.

Design 

The team does a gap analysis of the current process v new process and fleshes out the use case from the Discovery phase (input, output, test plan). The team prepares for the Development phase.

Develop

Critical team members work on the use case application. They create appropriate training material and documentation using the new application.

Test

 Team members develop test cases for the new application. Testing of courseware and documentation is done.

Implement

 After testing, the team deploys, supports, and maintains the platform and documentation for users. At the same time, they take note of issues and problems.

Measure

In the final phase, the team measures effectiveness and satisfaction. They make sure to deliver results in scheduled intervals (quarterly, semi-annual, or annual).

By taking a client through the innovation cycle, Scion Analytics determines the highest value and best use case for client needs with the CAP.

The Benefits Of Client Service Microservice

Time Savings

Client service microservice replaces human interaction with complete automation. It highly improves productivity because it runs without human involvement. The time savings for an enterprise are truly exponential. For example, Scion Analytics use cases have found that each time a client uses 1 microservice for every use it saves the client 8 hours. When 8 hours is saved in tangent with 30 employees at the same time, 240 hours is saved per use. The time savings grow exponentially when calculated annually and across the enterprise.

Automation

A user can analyze large amounts of documents quickly by setting up a client service microservice. By dropping the document into a folder, the user triggers the client service microservice to pick it up and process it. Once the client service microservice is done processing the document, it emails an output to the user. Conversely, without automation, a user would have to manually select the document and run the process.

Security

Another benefit that is particular to a client service microservice is security. By having a client service microservice installed on a client system, an enterprise ensures that sensitive and classified documents are protected.

How Microservice Enables Serverless Computing

To complement technological advances, another benefit of microservices is that it supports serverless computing. For example, if an enterprise has a system, it can have microservices running in the cloud. If this system is rolled out to a 10,000 client set at the same time it encourages 10,000 people to use the platform at the same time. This strains the servers and puts them in danger of crashing.

However, serverless computing in the cloud will give the enterprise the resource and computing power it needs. Serverless computing can only be set up if the system is written using microservices. Therefore, by adopting microservices, the enterprise also becomes more flexible with managing workload. If an enterprise is unsure about the amount of the workload on the servers or is using lots of servers but not provisioning them upfront, serverless computing will be the solution.

Conclusion

The Future of Work

By adopting microservices into the business process, an enterprise redefines the way work is done in the present and future.

By going through the customer engagement process, an enterprise ensures uniformity and consistency of processes and minimizes error. These are the features that are necessary for an enterprise to free up its workforce for more high-value tasks. This drives up employee satisfaction and as a result, it increases innovation in the enterprise. As the enterprise maximizes human intelligence and ingenuity, it opens itself up more to opportunity and scale. Thus, an enterprise that incorporates microservices is an enterprise transformed for the future.
