Databases & Analytics Summary in AWS
Relational Databases - OLTP: RDS & Aurora (SQL) • In-memory Database: ElastiCache • Key/Value Database: DynamoDB (serverless & NoSQL) • Warehouse - OLAP: Redshift (SQL) • Hadoop Cluster: EMR • Athena: query data on Amazon S3 (serverless & SQL) • Glue: Managed ETL (Extract Transform Load) and Data Catalog service • Database Migration: DMS
Scalability vs Elasticity (vs Agility)
Scalability: ability to accommodate a larger load by making the hardware stronger (scale up), or by adding nodes (scale out) • Elasticity: once a system is scalable, elasticity means that there will be some "auto-scaling" so that the system can scale based on the load. This is "cloud-friendly": pay-per-use, match demand, optimize costs • Agility: (not related to scalability - distractor) new IT resources are only a click away, which means that you reduce the time to make those resources available to your developers from weeks to just minutes.
Horizontal Scaling
Scaling horizontally takes place through an increase in the number of resources, such as adding more hard drives to a storage array or adding more servers to support an application.
Vertical Scaling
Scaling vertically takes place through an increase in the specifications of an individual resource, such as upgrading a server with a larger hard drive or a faster CPU

A financial services company must meet compliance requirements that mandate storing multiple copies of data in geographically distant locations. As the company uses S3 as its main storage service, which of the following represents the MOST resource-efficient solution for this use-case?
Use Cross-Region replication (CRR) to replicate data between distant AWS Regions Replication enables automatic, asynchronous copying of objects across Amazon S3 buckets. Buckets that are configured for object replication can be owned by the same AWS account or by different accounts. You can copy objects between different AWS Regions or within the same Region.
A space agency is using Amazon S3 to store their high-resolution satellite images and videos everyday. Which of the following should they do to minimize the upload time?
Use the Multipart upload API ----------------------------------- Multipart upload allows you to upload a single object as a set of parts. Each part is a contiguous portion of the object's data. You can upload these object parts independently and in any order. If transmission of any part fails, you can retransmit that part without affecting other parts. After all parts of your object are uploaded, Amazon S3 assembles these parts and creates the object. In general, when your object size reaches 100 MB, you should consider using multipart uploads instead of uploading the object in a single operation.
VPC (Virtual Private Cloud)
Used to create Private Network inside AWS; lets you provision a logically isolated section of the AWS Cloud where you can launch AWS resources in a virtual network that you define.
Which AWS service will you use to privately connect your VPC to Amazon S3?
VPC Endpoint Gateway
A financial services enterprise plans to enable Multi-Factor Authentication (MFA) for its employees. For ease of travel, they prefer not to use any physical devices to implement MFA. Which of the below options is best suited for this use case?
Virtual MFA device (Google Authenticator is an example of a Virtual MFA device)
Which of the following are components of an AWS Site-to-Site VPN? (Select two)
Virtual Private Gateway Customer Gateway --------------------- AWS Site-to-Site VPN enables you to securely connect your on-premises network or branch office site to your Amazon Virtual Private Cloud (Amazon VPC) Contents: Virtual Private Gateway Customer Gateway Customer Gateway device Transit Gateway
EC2
Virtual servers provides resizable compute capacity in cloud (IAAS)
With which services does CloudFront integrate to protect against web attacks?
WAF and SHIELD You can use AWS WAF web access control lists (web ACLs) to help minimize the effects of a distributed denial of service (DDoS) attack. For additional protection against DDoS attacks, AWS also provides AWS Shield Standard and AWS Shield Advanced.
Web Application Firewall (WAF)
WAF is a Layer 7 (HTTP)Application Firewall.
You are running an on-demand Linux EC2 instance, what timing is applied regarding billing?
With Linux EC2 instances, you pay per second of compute capacity. There is also a minimum of 60s of use.
An AWS user is trying to launch an EC2 instance in a given region. What is the region-specific constraint that the Amazon Machine Image (AMI) must meet so that it can be used for this EC2 instance?
You must use an AMI from the same region as that of the EC2 instance. The region of the AMI has no bearing on the performance of the EC2 instance
