Enterprise-class microservices

05.10.2022

It has been known for a long time that microservices are taking the world of software by storm. Many recognize their superiority over the concept of monolithic architecture. Is it right? Not quite. The determinant of a good system, designed with an individual enterprise in mind, is full adjustment to the specifics of this particular company. The monolith will be perfect for the start, the microservice will be appropriate where we deal with an extensive system structure. Both approaches have many advantages and disadvantages. Enterprise-class microservices can greatly improve application development. If, of course, they are properly managed.

Fast achievement of business goals of large companies

A system divided into independent microservices can be very dynamically developed. Each microservice contains a complete, closed structure and can function autonomously. Such high autonomy of microservices is reflected at the stage of designing specific solutions. Why? There are no restrictions on using the same technology to create all system components. We do not have to use the same tools to store data, etc. Such independent life cycles of microservices are perfect where investors want to be able to quickly develop specific system components. Of course, without having to upgrade the code of all software. It is particularly visible in the case of dynamically developing companies, where the needs change dynamically.

Meeting business goals that align with exponential growth requires software that can keep pace with your rapidly changing needs. In such situations, microservices work great. Development, implementation, data exchange, updates, modernization – all these activities can be carried out in relation to a specific microservice. It absolutely does not interfere with the actions of the others. In practice, the microservices architecture is based on maintaining high consistency of a single service and low coupling between other services. Thanks to this, making local changes is extremely easy here.

The priority is the clear structure of microservice architecture

Designing individual services with a view to achieving a specific business goal allows you to create a clear structure of microservice architecture.

That is why this approach works very well in large enterprises. To function efficiently, they need to use complex systems on a daily basis. The process of designing such advanced software is already based on a certain layering.Usually, conceptual work involves specialists from various departments in the company and programmers specializing in specific areas, such as: data processing, user experience design, etc. Individual microservices become a reflection of the assumptions adopted and the possibility of their effective implementation. Even if the resulting system is based on microservices placed in the middleware layer, updates do not require a huge amount of time and work. Of course, as with any system, it all depends on its scale.

When it reaches a certain degree of complexity, managing the entire system becomes a bit more complicated. This is related to very simple dependencies: we need to modernize a microservice that is already linked to its own constituent relationships and additionally connects to layers of other microservices. Often those that are subordinate to this microservice. In this case, the change requires the implementation of the full middleware layer[1].

Microservices and middleware

Want to know when middleware will work best? Let’s think about this for a moment:

– have a problem with handling various communication protocols, such as:

  • HTTP/REST
  • HTTP / SOAP
  • FTP / SFTP
  • SMTP
  • AMQP

– additionally, each of these protocols uses / can use a different data format, e.g .:

  • JSON
  • XML
  • flat files
  • binary data stream

– there is a large collection of already installed systems in your company, e.g .:

  • CRM system
  • HR system
  • an accounting system
  • sales system (E-Commerce)
  • ERP
  • mobile devices
  • desktops

If any of the issues described concern the functioning of your company, the best solution is to invest and create a MIDDLEWARE system. This solution will integrate all systems, which will allow you to unify communication with your company’s ecosystem, both through public and internal API. What are the additional advantages? There are a lot of them, for example:

  • ensuring the appropriate level of data security
  • full auditability
  • very good system efficiency
  • the ability to create new or optimize the operation of existing processes

Microservices in the eyes of technicians and business representatives

IBM has conducted microservices research on a group of over 1,200 IT executives and developers. 87% of technical specialists confirmed that the commitment and costs associated with migrating to microservices are worth the effort.[2] Two basic issues were also highlighted:

  • benefits received by development teams working in microservices architecture
  • ensuring better collaboration within the team developing a specific microservice

From the perspective of a team of technical employees, microservices offer great opportunities to create and develop various functionalities at the same time (the ability to work on several microservices at once). However, the profits for investors should not be forgotten

  • quick introduction of small changes – this allows you to efficiently achieve current business goals without long waiting for the implementation of new ideas
  • better isolation of errors – even if problems arise in one microservice, the work of the others does not have to be disrupted. Additionally, all repairs can be carried out more efficiently
  • easy code understanding – even the need to work with new programmers does not cause unnecessary delays in the ongoing modernization of a single microservice. The work is progressing smoothly because the source code is carefully isolated
  • easy application development – updates and development of an application based on the architecture of microservices is often cheaper than the modernization of the monolith. Additionally, it is easier to introduce more desirable technology here when it becomesavailable
