Q

Instance Store

A

An instance store provides temporary block-level storage for your instance. This storage is located on disks that are physically attached to the host computer. Instance store is ideal for temporary storage of information that changes frequently, such as buffers, caches, scratch data, and other temporary content, or for data that is replicated across a fleet of instances, such as a load-balanced pool of web servers.

An instance store consists of one or more instance store volumes exposed as block devices. The size of an instance store, as well as the number of devices available, varies by instance type.

Q

EFS (cloud and on-premise)

A

Amazon Elastic File System (Amazon EFS) provides a simple, scalable, fully managed elastic NFS file system 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, eliminating the need to provision and manage capacity to accommodate growth.

Amazon EFS offers two storage classes: the Standard storage class, and the Infrequent Access storage class (EFS IA). EFS IA provides price/performance that’s cost-optimized for files not accessed every day. By simply enabling EFS Lifecycle Management on your file system, files not accessed according to the lifecycle policy you choose will be automatically and transparently moved into EFS IA.

Q

CloudFormation (JSON / YAML)

A

AWS CloudFormation provides a common language for you to describe and provision all the infrastructure resources in your cloud environment. CloudFormation allows you to use programming languages or a simple text file to model and provision, in an automated and secure manner, all the resources needed for your applications across all regions and accounts. By turning your infra into code, you can deploy the code in your other regions.

For example, within a CloudFormation template, you say:
• I want a security group
• I want two EC2 instances using this security group
• I want an S3 bucket
• I want a load balancer (ELB) in front of these machines

Q

EBS Disk Types

A

General Purpose SSD – Recommended for most workloads; Can be used as system boot volumes; Best for development and test environments

Provisioned IOPS SSD – Meant for critical business applications that require sustained IOPS performance; Best used for large database workloads

Throughput Optimized HDD – Meant for streaming workloads requiring consistent, fast throughput at a low price, big data, data warehouses, and log processing. It cannot be a boot volume

Cold HDD – Meant for throughput-oriented storage for large volumes of data that is infrequently accessed, or scenarios where the lowest storage cost is important. It cannot be a boot volume

Q

Amazon Aurora Backtrack

A

Just a feature of Amazon Aurora which allows you to restore or “backtrack” a DB cluster to a specific time, without restoring data from a backup. Hence, this is not a suitable option to host a Microsoft SQL Server database. This feature somewhat rewinds the DB cluster to the time you specify. Backtracking is not a replacement for backing up your DB cluster so that you can restore it to a point in time.

Q

Aurora

A

Primarily used as a MySQL or PostgreSQL-compatible relational database engine that combines the speed and reliability of high-end commercial databases with the simplicity and cost-effectiveness of open source databases. It is designed to transparently handle the loss of up to two copies of data without affecting database write availability and up to three copies without affecting read availability.

Amazon Aurora storage is also self-healing. Data blocks and disks are continuously scanned for errors and repaired automatically.

Although you can use the AWS Schema Conversion Tool to migrate your existing Microsoft SQL Server to Amazon Aurora, this service is still not applicable in this scenario since the requirement is urgent and you will be hosting a brand new database, not an already existing one.
