In 2001, development delays, coding challenges, and service interdependencies inhibited Amazon’s ability to meet the scaling requirements of its rapidly growing customer base. Now, a lot of startups, and even projects inside of big companies, start out this way … But over time, as that project matures, as you add more developers on it, as it grows and the code base gets larger and the architecture gets more complex, that monolith is going to add overhead into your process, and that software development lifecycle is going to begin to slow down.” ( source ) It was architected in multiple tiers, and those tiers had many components in them … But they’re all very tightly coupled together, where they behaved like one big monolith. “If you go back to 2001,” stated Amazon AWS senior manager for product management Rob Brigham, “the retail website was a large architectural monolith.” Here’s how Amazon’s senior product manager described the situation: The tight connections between – and within – the multi-tiered services that comprised Amazon’s monolith meant that developers had to carefully untangle dependencies every time they wanted to upgrade or scale Amazon’s systems. In the early 2000s, Amazon’s retail website behaved like a single monolithic application. The enterprises below used microservices to resolve key scaling and server processing challenges. Let’s look at some examples of microservices in action. *Read our complete guide to microservices for more detailed information on this application architecture. Use container orchestration tools like Kubernetes to manage the allocation of system resources for each microservice. An iPaaS like DreamFactory can play an essential role in this step. Loosely integrate the microservices via API gateways so they work in concert to form the larger application. ![]() Each microservice answers to a single function – like search, shipping, payment, accounting, payroll, etc. These usually run in a container on a cloud server. Develop the microservicesĭevelop each function of the application as an autonomous, independently-running microservice. Study the operation of the monolith and determine the component functions and services it performs. Here are the steps to designing a microservices architecture: 1. They can do this without necessarily incurring service outages, without negatively impacting other parts of the application, and without needing to refactor other microservices. This architecture offers greater agility and pluggability because enterprises can develop, deploy, and scale each microservice independently. They loosely connect via APIs to form a microservices-based application architecture. Building a Microservices ArchitectureĪt this point, developers may choose to divide the functionality of a monolith into small, independently-running microservices. The more upgrades performed, the more complicated the programming becomes until upgrades and scaling are virtually impossible. ![]() This makes upgrades a time-consuming and expensive process. Changing or adding a single feature in a monolith can disrupt the code for the entire application. Since the code for these functions is woven together, it’s difficult to untangle. All of the programming for those functions resides in a cohesive piece of application code. The monolith carries out a number of functions. Most enterprises start by designing their infrastructures as a single monolith or several tightly-interdependent monolithic applications. But first, let’s look at the general circumstances that inspire enterprises to use microservices in the first place. In this article, we’ll explore the microservices examples of these wildly successful enterprises. This helped to quickly achieve scaling advantages, greater business agility, and unimaginable profits. Over time, these enterprises dismantled their monolithic applications and refactored them into microservices-based architectures. Some of the most innovative and profitable enterprises in the world – like Amazon, Netflix, Uber, and Etsy – attribute their IT initiatives’ enormous success in part to the adoption of microservices.
