Are there different type of volume other than EBS volume in aws?

Question 1

In terms of volumes for AWS that I know of there are two:

EBS Volumes. These are managed drives for your EC2 instances. You can boot off them, snapshot them, and move them between machines. EBS volumes come in two flavors: Standard and PIOPS. The billing between the two is slightly different, as are their performance characteristics. Unlike Ephemeral volumes the data written to EBS is durable. You can create EBS drives in a number of ways.
Ephemeral Volumes. These are volumes that come-and-go along with your EC2 instance. Anything you write to them will be lost if the EC2 instance is shutdown or moved.

AWS has a number of other storage offerings (RDS, S3, DynamoDB, Glacier) but they're not focused on offering products that act like hard disks.

Question 2

It depends on your definition of "Volume". There are actually 4 types of storage available on AWS, though only Instance Storage and EBS qualify as "Volumes".

1: Instance Storage - This is storage tied directly to an instance, like a hard drive on a physical machine. http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/InstanceStorage.html

2: EBS - You could think of EBS like an external drive on a physical machine. It can be detached and attached to another instance. http://aws.amazon.com/ebs/

3: S3 - This is an http based storage option. It is extremely reliable, but cannot be mapped as a volume directly, files must be retreived via an http request. http://aws.amazon.com/s3/

4: Glacier - This is meant to be a replacement for backup tapes. It is very slow to access, but very reliable. It is only intended for backup purposes as there are heavy fees for frequent access. http://aws.amazon.com/glacier/

Amazon Elastic Block Store:- Amazon Elastic Block Store (Amazon EBS) provides persistent block storage volumes for use with Amazon EC2 instances in the AWS Cloud. Each Amazon EBS volume is automatically replicated within its Availability Zone to protect you from component failure, offering high availability and durability. Amazon EBS volumes offer the consistent and low-latency performance needed to run your workloads. With Amazon EBS, you can scale your usage up or down within minutes—all while paying a low price for only what you provision.

Amazon Elastic File System:- Amazon Elastic File System (Amazon EFS) provides a simple, scalable, elastic file system for Linux-based workloads for use with AWS Cloud services and on-premises resources. It is built to scale on demand to petabytes without disrupting applications, growing and shrinking automatically as you add and remove files, so your applications have the storage they need – when they need it. It is designed to provide massively parallel shared access to thousands of Amazon EC2 instances, enabling your applications to achieve high levels of aggregate throughput and IOPS with consistent low latencies. Amazon EFS is a fully managed service that requires no changes to your existing applications and tools, providing access through a standard file system interface for seamless integration. Amazon EFS is a regional service storing data within and across multiple Availability Zones (AZs) for high availability and durability. You can access your file systems across AZs and regions and share files between thousands of Amazon EC2 instances and on-premises servers via AWS Direct Connect or AWS VPN.

Amazon EFS is well suited to support a broad spectrum of use cases from highly parallelized, scale-out workloads that require the highest possible throughput to single-threaded, latency-sensitive workloads. Use cases such as lift-and-shift enterprise applications, big data analytics, web serving and content management, application development and testing, media and entertainment workflows, database backups, and container storage.

Amazon FSx for Lustre:- Amazon FSx for Lustre is a fully managed file system that is optimized for compute-intensive workloads, such as high performance computing, machine learning, and media data processing workflows. Many of these applications require the high-performance and low latencies of scale-out, parallel file systems. Operating these file systems typically requires specialized expertise and administrative overhead, requiring you to provision storage servers and tune complex performance parameters. With Amazon FSx, you can launch and run a Lustre file system that can process massive data sets at up to hundreds of gigabytes per second of throughput, millions of IOPS, and sub-millisecond latencies.

Amazon FSx for Lustre is seamlessly integrated with Amazon S3, making it easy to link your long-term data sets with your high performance file systems to run compute-intensive workloads. You can automatically copy data from S3 to FSx for Lustre, run your workloads, and then write results back to S3. FSx for Lustre also enables you to burst your compute-intensive workloads from on-premises to AWS by allowing you to access your FSx file system over Amazon Direct Connect or VPN. FSx for Lustre helps you cost-optimize your storage for compute-intensive workloads: It provides cheap and performant non-replicated storage for processing data, with your long-term data stored durably in Amazon S3 or other low-cost data stores. With Amazon FSx, you pay for only the resources you use. There are no minimum commitments, upfront hardware or software costs, or additional fees.

Amazon FSx for Windows File Server:- Amazon FSx for Windows File Server provides a fully managed native Microsoft Windows file system so you can easily move your Windows-based applications that require file storage to AWS. Built on Windows Server, Amazon FSx provides shared file storage with the compatibility and features that your Windows-based applications rely on, including full support for the SMB protocol and Windows NTFS, Active Directory (AD) integration, and Distributed File System (DFS). Amazon FSx uses SSD storage to provide the fast performance your Windows applications and users expect, with high levels of throughput and IOPS, and consistent sub-millisecond latencies. This compatibility and performance is particularly important when moving workloads that require Windows shared file storage, like CRM, ERP, and .NET applications, as well as home directories.

With Amazon FSx, you can launch highly durable and available Windows file systems that can be accessed from up to thousands of compute instances using the industry-standard SMB protocol. Amazon FSx eliminates the typical administrative overhead of managing Windows file servers. You pay for only the resources used, with no upfront costs, minimum commitments, or additional fees.
