Microservices have completely changed the way technology is delivered and used in companies, both large & small, intending to ease the complexities of hardware, OS, and other development toolkits that are used or available on a network.
Both the consumers or the providers can leverage the benefits of microservices. Consuming them is easy for any organization to use in their software architectures. There are thousands of services like these that deliver anything from providing a location’s data, to tracking delivery packages. Today, modern consumer apps are not just about impressive user interfaces and complex logic which complete the tasks by managing the interactions among microservices. Many of these microservices require a “key” or registration, some may require a payment method, however, the cost of these is not as much as building the code on your own. The “free-tier” in these services is more than sufficient for you to develop.
As your developers develop and enhance their understanding of consuming & building microservices, your organization would be able to identify key services that need to be delivered both internally as well as externally.
For example, to provide your customer information to your sales team or customer support team, you can create an internal microservice. As for the public microservice, you can develop the one that provides your consumers’ product information, their order status, etc.
Avoid these mistakes while building software using microservices
The biggest stumbling block in microservices is, perhaps, forgetting about the “micro” part of the equation. It may be tempting to create a single service to perform multiple tasks & act more like a switch between legacy systems, rather than a service that performs discrete tasks. When you create these “monster services,” they are generally only useful in a limited number of applications, rather than small general-purpose services that can be used in multiple places.
If you develop a complex and multi-stage service, you need to start by creating simple services first that can be combined. By creating smaller building blocks like these, you will have more scalable options.
Another common mistake that organizations make is creating a service designed for a single application. For example, if I need an order tracking number, you might want to create an order tracking number microservice, which accepts an order number & returns the tracking number. It is best to create an order data microservice that provides your consumers general information about orders, including the tracking numbers that can be used in various applications.
Incorporating microservices in your technology stack
Businesses (all sizes) should consider incorporating microservices instead of using custom code whenever available. Microservices have leveled the tech environment to great extent. Small businesses used to be at a serious disadvantage in the face of “large companies” who could afford large data centers along with the employees who can run them. Now, organizations with 1 or 100,000 people can have the same access to the Amazon and Google APIs and use the assets of these tech giants to their advantage. For smaller companies, microservices can act as “power multipliers” because they allow you to quickly build complex applications by using services created and maintained by others. Thousands of start-ups even creatively combine existing services or create services to fill specific niches and turn them into a business.
Larger companies should consider investing in microservices to reduce their reliance on legacy and proprietary systems. By providing internal microservices, they are no longer dependent on specific hardware or software vendors and can upgrade the components of their infrastructure without affecting a large number of applications. In addition, the use of microservices enables legacy systems and data to drive new creative tools. With the right microservices, you can quickly develop mobile applications to safely and easily access data previously locked on mainframes. Microservices can also reduce IT reliance on new tools and applications. If marketers want to launch a new product catalog and you have a microservice, they no longer rely on IT to write interfaces or provide scarce resources.
Final Words
Microservices can seem complex and confusing, leading many IT leaders to believe that they are a good idea to explore the “ultimate”. As you have seen before, they can be as simple as clicking a link. Companies can now easily convert their large monolithic apps into small components with the help of microservices, then package and deploy them separately. These microservices provide organizations with more agile, scalable, and resilient apps and also enable you to update, change, as well as redeploy them, way faster. This is where tools like Docker and Kubernetes come into play and help the companies.
Kubernetes has spread like fire in the market and more & more organizations continue to adopt it every year. Many global companies have already been using Kubernetes in their massive scale production. On the other hand, Docker is another great piece of technology that has seen tremendous adoption growth over the years. This is the reason for an astounding demand for Docker and Kubernetes around the globe as organizations worldwide are integrating these two major platforms for their containers & microservices.
