Most of you use APIs without even understanding it. What is API, how it works and what can it do? IT Svit explains API basics from a DevOps point of view.

The majority of people utilize APIs– Application Shows Interfaces without even focusing. Whenever you schedule a space, order a pizza online from your mobile app or carry out actually any other action online– you utilize API somewhere along the method. Today we go over why API adoption is essential for modern-day company, how API works from a DevOps viewpoint, types of APIs existing, what are the current API trends of 2020 and what are API execution usage cases and advantages.

Why APIs are essential

From a software application engineering standpoint, API is an intermediary between two independent systems enabling hem to communicate with each other and exchange data. Much like a USB cable linking your smartphone to your laptop allows integrating data, submitting pictures to the laptop and charging your smart device battery along the way, dealing with APIs allow software application engineers to run a set of standardized functions that will work as meant in any business situation.

This efficiently suggests that when building a new services or product and developing its future functionality you can minimize the variety of unique code that requires to be composed, as you can use a substantial publicly readily available library of common APIs (15,000 according to Programmable Web) as structure blocks and implement basic functions like authentication quickly, significantly minimizing time-to-market for your jobs. API enables avoiding reinventing the wheel while constructing systems that work dependably regardless of the facilities behind their respective parts.

Thus said, if you have a tradition system operating on on-prem servers with hardcoded functionalities described in code, replacing these functionalities with the matching APIs enables moving your IT operations to a lot more cost-efficient virtual servers in the cloud to delight in the security and scalability without needing to deal with maintenance and manual server configuration. If your charge card payment processor is a Java software application that operates on a tradition Oracle-based app server, utilizing API allows moving to the most recent version of the Node.JS server-side Javascript server hosted at AWS or Microsoft Azure, for example.

To cover it up, utilizing APIs enables the designers to be considerably more efficient, as implementing any function on a regular basis needs just utilizing the ideal API and composing a few lines of code to make the needed API call. This way new features can be constructed, checked and released within days and weeks, not months and years.

How API works from a DevOps point of view

API is a container of code with endpoints and webhooks that enable making API calls from external systems. API is a great component for DevOps procedures, as API containers can be stored as Docker Computer registry images and composed into Docker containers on demand, or kept inactive to reduce the resource intake up until they have to operate. APIs can be introduced and ran as a separate microservice and take advantage of all benefits of this technique– security, repeatability, scalability, transparency. This is essential, as it combines completely with DevOps principles of CI/CD, IaC and service meshes.

Service meshes have rather evolved in complexity over the last few years, and rather of additional control plane they were initially presented as, service meshes now represent complex microservice environments with “dumb CI pipelines and smart endpoints”. As long as the API is set up correctly, it matters not what information is sent, making the same reasoning and system components appropriate in a wide variety of organization scenarios. This allows conserving money at scale instead of composing the code from scratch for every brand-new service case.

Types of APIs

There are numerous important branches of APIs used for numerous functions:

REST APIs are without a doubt the most popular sort of Advanced Programs Interfaces, as they are required to make it possible for smooth interoperability in between a myriad of components for various web services. Over 70% of all openly readily available APIs use REST for JSON processing, due to its dependability, speed of performance, and ability to scale modularly, without impacting other system parts.

REST or Representational State Transfer stands for a software style that enables stable and foreseeable information operations by supplying a uniformed set of guidelines for data operations. The payload or the information to be processed is specified in the demand and is delivered in HTTP, JSON or XML format utilizing standardized HTTP operations like GET, PUT, POST, DELETE, and so on. REST API demand includes 4 main parts:

Of course, there are countless exclusive APIs used in various systems to perform app-specific operations. This leads to an emerging API economy, where the companies with the necessary expertise can write an API of among the types noted above for you, enhance the performance of the existing one or change an outdated bespoke API with some fresh common option to decrease your operational expenses and provide an enormous increase to your company efficiency.

Most current API patterns of 2020

APIs changed from custom-made executions of recurring code functions into standardized sets of rules that streamline the operations of uncountable web services and make the IT market a lot more productive as a whole. They continue to progress due to a substantial and enthusiastic neighborhood that utilizes them in their operations and constantly discovers brand-new methods of API implementation to speed up the software delivery procedure.

In autumn of 2019, Linux foundation has held the first-ever API Spec Conference in Vancouver. The even has collected API professionals and lovers who shared their experience and vision on and has actually laid out the major trends of API advancement in 2020:

API usage cases

We have quickly pointed out several API use cases above, and now we wish to share how IT Svit handles APIs in our daily workflows. As one of the leading Managed DevOps Solutions Providers worldwide, we deal with all sorts of APIs in our jobs.

Hence said, APIs are excellent tools for building modular and versatile applications and services and guarantee their smooth interaction with other web platforms. IT Svit has long-term experience with dealing with all API-related jobs and we can help you accomplish your task successfully.
