A survey carried out by Nginx, revealed that about 70% of businesses either use or think about using microservices… This AWS service automatically spins up more elastic instances if the request volume increases and turns off unused ones. Then in section 2.2, a more detailed microservices architecture of Backend will be described to demonstrate how Netflix handles availability and scalability at global scale. Adhering to these foundational microservice building blocks helped Netflix develop its architecture. There are other components, Ribbon (Client Side Routing), Feign (Declarative REST Client), Hystrix (Latency and Fault Tolerance) we will be discussing about them in subsequence parts. Section 2 will describe a possible Netflix system architecture learnt from various online sources. The microservice architecture enables the continuous delivery/deployment of large, complex applications. Netflix is one of the first companies to have successfully migrated from a traditional monolithic to cloud-based microservices architecture. By definition, availability of a system is measured in terms of how many times a response would be fulfilled for a request within a period of time, without guarantee that it contains the most recent version of the information. With AWS scaling can be done within a couple of minutes without any user involvement. MySQL databases are used for movie title management and transactional/billing purposes. Outbound Filters can be used for tracking metrics, decorating the response to the user or adding custom headers. Each microservice represents a single product feature that can be updated independently of the other microservices … The selected OCA server accepts requests from the client and starts streaming videos. Netflix team has spent a lot of time designing the Application API component since it is correspondent to Netflix core business functionalities. In section 2.1, an overall architecture is capable of streaming videos, called playback architecture, after a subscriber clicks the Play button on his or her apps. The other parts such as caching and load balancing also help increasing scalability have been mentioned in Section 4. We use cookies to ensure you have the best browsing experience on our website. Endpoint Filter can be used to return static resources or route the request to appropriate Origin or Application API for further processing. Netflix had built and operated Open Connect efficiently by bringing the content that people want to watch as close as possible to where they want to watch it. Even Amazon and Netflix have jumped on the bandwagon! Microservices architecture is a never ending story. Application API plays a role of an orchestration layer ([18]) to the Netflix microservices. Some of the components of Backend with their corresponding AWS services are listed as follows: Open Connect CDN is a network of servers called Open Connect Appliances (OCAs) optimized for storing and streaming large videos. There are two core services – movie-service and review-service, that will implement a simple movie library and a review system holding reviews for movies. In return, the Application API uses Hystrix commands to time-out calls to microservices, to stop cascading failures and isolate points of failures from others. After a … When it comes to cloud computing today it is no surprise that Netflix has managed to come out as a technology leader. Netflix is one of the first companies to have successfully migrated from a traditional monolithic to cloud-based microservices architecture. The diagram in Figure 2 represents a possible microservices architecture at Netflix which I have derived from several online sources ([11, 13, 14]): The described architectures help us get a general understanding of how different pieces organize and work together to stream videos. The solution was accomplished using Amazon Web Service (AWS), which promised to provide large computing resources and data centers with guaranteed security and reliability. Microservices is a specialization of an implementation approach for service-oriented architectures (SOA) used to build flexible, independently deployable software systems. As I have described in previous sections, Backend handles almost everything, ranging from sign up, login, billing to more complex processing tasks such as video transcoding and personalized recommendations. API Gateway Service component communicates with AWS Load Balancers to resolve all requests from clients. I have added the Netflix OSS components to our Reference Architecture of a Microservices based Application we saw earlier. What was your GATE (CSE) preparation story? In this scenario, the forwarded request from API Gateway Service is handled by Play API. Now, let’s see how microservices are created and how they interact with each other using spring-boot, spring-cloud, and Netflix OSS to implement a minimalist microservices demo application. Microservices can send events for tracking user activities or other data to the Stream Processing Pipeline for either real-time processing of personalized recommendation or batch processing of business intelligence tasks. Playback Apps service must determine that Play request would be valid in order to view the particular video. MicroServices has caught on as the design pattern of choice for many companies at scale. Microservices can save to or get data from a data store during its process. This study is organized as follows. In order to support both lightweight and heavy workloads running on the same underlying infrastructure, Netflix has chosen microservices architecture for their cloud based system. Netflix operates based on Amazon cloud computing services (AWS) and Open Connect, its in-house content delivery network ([1]). Microservices Architecture: Use Cases. These servers periodically report health metrics optimal routes they learned from IXP/ISP networks and what videos they store on their SSD disks to Open Connect Control Plane services on AWS. , processing, aggregating, and other configurations, LinkedIn — all these companies chose to decentralize their architecture soon!
