How to Create Apps Quickly Using Microservices

The major goal of this series on microservices is to get you to the point where you can choose an appropriate cloud-based pilot scheme for your team. Why is it important? Adopting a cloud platform requires a significant commitment and the validation that comes from earlier work on one or more minimum viable products.

Gartner researchers recently stressed the necessity of beginning cloud-native development as soon as possible after any initial migration of current workloads.

Understanding Microservices

A majority of people on the planet now primarily use mobile devices to access the internet. All market incumbents have been cautioned that their clients' expectations would change as a result of increasingly inventive user experiences. Rapidly developing consumer relationships through mobile applications is now a business planning axiom.

Mobile first is insufficient: Customers may put up with a fantastic mobile version of your current website for a while, but you need to consider how long you can make them wait for additions that improve their everyday life. Your innovation could easily turn into a copycat product if putting your ideas into practice takes months, as is frequently the case with a monolithic program that demands coordinated effort from numerous teams. There will always be a more nimble rival trying to take advantage of the situation.

It is painfully evident that development teams must speed up the process through which they provide new benefits to users. Even the fastest and most effective DevOps program must be prepared to fail in the sphere of actual user experience because no one can completely foresee user behavior. Based an on analysis of transparent usage data, quickly rebuilding, changing, and enhancing key components of the user experience is a major priority.

Therefore, creating cloud-based apps using a microservices paradigm is extremely effective. It provides a team the flexibility to take full ownership of the entire cycle (concept, development, deployment, and monitoring) for each component of an app, allowing for precise iteration of any aspect of the user experience that is underperforming as evidenced by data gathered from monitoring what users are actually doing. The DevOps process turns into a dynamic dialogue with users in the field, almost like a conversation.

Steps in Building Microservices Applications

For effective app deployment in the mobile services era, DevOps is a prerequisite, as is failing quickly and iterating swiftly. In a continuous development and development lifecycle, they indicate application designs that provide seamless client interactions while decoupling services from one another.

While incumbent businesses frequently have to start by modifying an existing monolith, startups generally have an advantage in designing greenfield cloud-native apps using a microservices model combined with DevOps tools and processes.

Let’s examine a specific illustration.

In this instance, an online store sought to split up a monolith into microservices so that it could quickly update and add new features while also learning more about its customers.

The redesign of the entire app started there since browsing the online catalog offered urgent business concerns to solve:

Pilot Task: Determine and Deploy a Better Way to Handle the Catalog

Customers were unable to quickly discover product information with the current app, and the company was prevented from sharing data with other websites.

The team created a single microservice for the company catalog as a proof of concept for the microservices strategy using the methods described below:

To complete the work, create a new continuous continuation/integration development model.

Import data into an elastic search to discover new methods to explore their information and unearth new data.

Connect the new search to the current webpage.

The catalog was still connected with the ordering components at this point since they executed core business logic and were too complicated to be broken apart without more work. But after a fruitful trial, the team was persuaded of the worth of microservices and chose to broaden the scope of app transformation.

Task 2: Discover More About the Client

By figuring out how to reorient the company such that it focuses on customers rather than inventory, the team was able to learn more about the client and develop a microservice account.

The decision to employ an unstructured database became clear when it was discovered that customer experience could be improved over time based on marketing, analytics, and cognitive data. In order to manage the unstructured data, they created a new customer model and employed a NOSQL database (such as Cloudant or Mongo DB).

Task 3: Improve the User Experience

The group developed a brand-new native mobile application and a fresh front end for mobile and web access. The entire user experience was significantly improved, despite the catalog’s reliance on the outdated ordering code.

Task 4: Modify Order Microservice Access

The group developed new mobile order APIs and incorporated them into current transactions. The company made the decision to develop an adaptor microservice that accessed the current on-site ordering system of records. They also integrated it with fresh payment systems and procedures using the adaptor.
