Build a multi-tenant serverless architecture in Amazon OpenSearch Service

What Is Serverless Architecture Template All About?

Build multi-tenant serverless architecture OpenSearch Service template is for creating a design where you don't have to host your own servers. You instead use managed services of AWS. It uses Amazon OpenSearch Service as the main search engine.

This is how it functions in a simple way:

• Your raw data is stored on Amazon S3.

• A small program, built with AWS Lambda, picks up that data and sends it to OpenSearch for indexing.

• Another Lambda function helps you in searching for data.

• API Gateway is the public entry point for secure communication between your system and users.

• CloudWatch monitors the performance and displays logs in case you would like to see what goes on behind the scenes.

All of this is achieved without your having to install or deal with any physical server. That is serverless.

Why Serverless Architecture Template Is a Game Changer?

consistently, if you had to serve multiple customers, you would require dissimilar setups for each customer or tenant. That means more servers, more expense, and more work to manage it all. This template removes all headaches. With OpenSearch Serverless multi-tenancy, you can index and search data for multiple tenants in a single location, through a shared but organized index. You only pay for what you consume since the architecture is serverless. The more data you have, the more it automatically scales. When your traffic is low, you are not wasting resources.

It also keeps things secure and organized. Each tenant data is dealt with hard using IAM rules, and all running inside a VPC, so it is safe. Built in CloudWatch metrics and logs allow you to easily see how the system is operating. For teams and companies, that translates to being able to focus on developing your product and serving your users instead of wasting time on server setup and authority.

Who Can Use Serverless Architecture Template, and When?

This template can be used by anyone who is charged with managing search data for more than one group, team, or customer.

It is best for:

• A startup developing a product for several buyers.

• A new enterprise that will have to go through gigantic data sets.

• A development team that requires saving time and not learning everything from scratch.

The best time to use this template is when you are beginning a new project that includes search functionality or when you think of moving your current system to a simple to maintain, and cost effective one.

What Are The Main Components Of The Template For Serverless Architecture?

These are the building blocks of this architecture and what they accomplish:

• Amazon S3: Where the data is stored once it is uploaded.

• Client Browser: This is the client's end, where he/she can upload information or retrieve it.

• API Gateway: It is a secure front door that accepts all user requests.

• AWS Lambda Index Function: A small script that receives data from S3 and forwards it to OpenSearch index.

• AWS Lambda Search Function: Yet another function that deals with search queries and returns results.

• Amazon OpenSearch Service: The primary service where data is stored and queried quickly.

• Pooled Index: A shared index containing data of all the tenants but keeping it sorted.

• VPC: A private network, maintaining communication security in the AWS domain.

• CloudWatch Logs: Shows you what's happening in the system so you can debug if needed.

• CloudWatch Metrics: Gives you system performance data and charts.

• IAM Roles: Decides who has access to what but ensures security.

• Share Icons and Annotation Tools: Help you and your team to collaborate while designing Cloudairy.
