Couchbase Server is a NoSQL document database with a distributed architecture for performance, scalability, and availability. It enables developers to build applications easier and faster by leveraging the power of SQL with the flexibility of JSON.

Miri Infotech is launching a product which will configure and publish Couchbase, a NoSQL document database which is embedded pre-configured tool with Ubuntu and ready-to-launch AMI on Amazon EC2 that contains Couchbase Server, Hadoop, Linux.

Developers around the world build enterprise web, mobile, and IoT applications on the Couchbase data management platform to support massive data volumes in real time. The Couchbase platform includes Couchbase Server, Couchbase Lite - the first mobile NoSQL database, and Couchbase Sync Gateway.

Couchbase makes it easy for developers to build enterprise applications on NoSQL using N1QL, a declarative query language that extends SQL for JSON. Couchbase also makes it easy to operate at any scale, with elastic scalability and configurable cross data center replication to increase data locality and availability. All Couchbase products are open source projects.

Couchbase investors include Accel Partners, Adams Street Partners, Ignition Partners, Mayfield Fund, North Bridge Venture Partners, Sorenson Capital and WestSummit. The company has raised $146 million in seven rounds of funding with its most recent round of $30 million in March 2016.

Couchbase is part of the $35 billion database market and has quickly built a reputation among the Fortune 500 as the performance and scalability leader among NoSQL vendors. The database market is highly competitive, with legacy vendors like Oracle being challenged by NoSQL vendors such as Couchbase, as well as competitors like DataStax and MongoDB. According to a report from Allied Market Research, the NoSQL database market is expected to reach $4.2 billion by 2020, a CAGR of 35 percent from 2014-2020.

You can subscribe to Couchbase Server, an AWS Marketplace product and launch an instance from the Couchbase Server product's AMI using the Amazon EC2 launch wizard.

To launch an instance from the AWS Marketplace using the launch wizard
  • Open the Amazon EC2 console at https://console.aws.amazon.com/ec2/
  • From the Amazon EC2 dashboard, choose Launch Instance.
    On the Choose an Amazon Machine Image (AMI) page, choose the AWS Marketplace category on the left. Find a suitable AMI by browsing the categories, or using the search functionality. Choose Select to choose your product.
  • A dialog displays an overview of the product you've selected. You can view the pricing information, as well as any other information that the vendor has provided. When you're ready, choose Continue.
  • On the Choose an Instance Type page, select the hardware configuration and size of the instance to launch. When you're done, choose Next: Configure Instance Details.
  • On the next pages of the wizard, you can configure your instance, add storage, and add tags. For more information about the different options you can configure, see Launching an Instance. Choose Next until you reach the Configure Security Group page.
  • The wizard creates a new security group according to the vendor's specifications for the product. The security group may include rules that allow all IP addresses ( access on SSH (port 22) on Linux or RDP (port 3389) on Windows. We recommend that you adjust these rules to allow only a specific address or range of addresses to access your instance over those ports.
  • When you are ready, choose Review and Launch.
  • On the Review Instance Launch page, check the details of the AMI from which you're about to launch the instance, as well as the other configuration details you set up in the wizard. When you're ready, choose Launch to select or create a key pair, and launch your instance.
  • Depending on the product you've subscribed to, the instance may take a few minutes or more to launch. You are first subscribed to the product before your instance can launch. If there are any problems with your credit card details, you will be asked to update your account details. When the launch confirmation page displays


Couchbase Server, originally known as Membase, is an open-source, distributed multi-model NoSQL document-oriented database software package that is optimized for interactive applications. It is a NoSQL document database with a distributed architecture for performance, scalability, and availability. It enables developers to build applications easier and faster by leveraging the power of SQL with the flexibility of JSON.


The sizing of your Couchbase Server cluster is critical to its overall stability and performance. While there are obviously many variables that go into this, the idea is to evaluate the overall performance and capacity requirements for your workload and dataset. Then divide that into the hardware and resources you have available. Your application wants the majority of reads coming out of the cache, and the I/O capacity to handle its writes. There needs to be enough capacity in all areas to support everything the system is doing while maintaining the required level of performance.

This guideline will refer to five determining factors one should be aware of when sizing a Couchbase Server cluster: RAM, Disk (I/O and space), CPU and network bandwidth.Every Couchbase node consists of a data service, index service, query service, and cluster manager component. Starting with the 4.0 release, the three services can be distributed to run on separate nodes of the cluster if needed.


Couchbase Server specifies limits and limitations that may affect server usage and implementation. Depending on the size of the documents passed to the view engine, the performance of Couchbase Server may be affected.

  • Unpredictable behavior may result if you change Couchbase Server topology or modify connected buckets, for example, by deleting or flushing a bucket in Couchbase Server. These operations are not supported. If you must change your Couchbase Server cluster or buckets, first DROP your Analytics Datasets and then recreate them after your changes have been completed.
  • The SELECT DISTINCT operation is not supported.
  • The MINUS, INTERSECT, UNION without ALL operations are not supported.
  • The OFFSET without a LIMIT statement is not supported.
  • If you use add a GROUP BY expression in the SQL format, the expression for the GROUP BY key in the SELECT clause must be identical to the GROUP BY key expression.
  • The PREPARE statement is not supported.
  • Data Manipulation Language (DML) operations such as INSERT, DELETE, UPSERT, UPDATE do not apply to shadow datasets (which mirror data in Couchbase Server) and are therefore not supported.

Usage / Deployment Instruction

Step 1 : Open Putty for SSH

Step 2 : Open Putty and Type <instance public IP> at “Host Name”

Step 3 : Open Conncetion->SSH->Auth tab from Left Side Area

Step 4 : Click on browse button and select ppk file for Instance and then click on Open
