Q

What is Multi Part

A

AWS multipart upload is a feature of Amazon S3 (Simple Storage Service) that allows you to upload a single object as a set of parts. Each part is a contiguous portion of the object’s data and is uploaded independently. Once all parts are uploaded, they are automatically reassembled into a single object.

Q

What is S3 accelerator

A

Amazon S3 Transfer Acceleration is a feature of Amazon S3 that enables fast, easy, and secure transfers of files over long distances between your client and an S3 bucket. It leverages Amazon CloudFront’s globally distributed edge locations to accelerate your uploads to S3. When data arrives at an edge location, it is routed to Amazon S3 over optimized network paths.

Q

How does caching with cloud front work

A

Amazon CloudFront is a content delivery network (CDN) service that speeds up the delivery of your content to users around the world. It does this by caching copies of your content in strategically placed edge locations across the globe.

A cache check checks to see if the content already exists. If it does, it uses that and if not, it requests from the origin server

Q

How can metrics help with auto scaling?

A

In AWS, Auto Scaling is a service that helps you automatically adjust the number of compute resources, such as EC2 instances, to maintain application performance and optimize costs. Metrics are a critical component of Auto Scaling, as they provide the information needed to make decisions about scaling actions.

Q

Read Replicas vs. Multi AZ Deploy

A

Read Replicas

Improve performance by offloading read traffic from the primary database instance.

Facilitate scaling of read-intensive database workloads.

Enable data distribution for read-heavy applications

Multi AZ

Enhance availability and reliability by automatically replicating data across different Availability Zones (AZs).

Provide automated failover support for database instances.

Use Read Replicas if your primary goal is to scale read operations and distribute load among multiple instances, especially for read-heavy workloads.

Use Multi-AZ Deployments if your primary goal is to enhance database availability and reliability, with automated failover to a standby instance in the event of failure. Multi-AZ is crucial for production workloads where high availability and automatic recovery from failures are critical.

Q

What is Transit Gateway

A

AWS Transit Gateway is a network transit hub that you can use to interconnect your Amazon Virtual Private Clouds (VPCs) and on-premises networks. It acts as a central hub that simplifies network architecture, allowing you to manage and route traffic efficiently across multiple networks.

19
Q

What is cloud hub

A

AWS CloudHub is a feature of AWS that facilitates the connection of multiple Amazon Virtual Private Clouds (VPCs) and on-premises networks over a secure, scalable, and highly available network infrastructure. It is particularly useful for organizations that have branch offices, remote locations, or multiple on-premises data centers that need to connect securely to AWS and to each other

20
Q

Data Sync

A

AWS DataSync is a managed data transfer service that simplifies, automates, and accelerates moving data between on-premises storage systems and AWS storage services. It is designed to handle large-scale data transfers in a fast and reliable manner, supporting a variety of use cases such as data migration, data processing, and backup and recovery.

21
Q

Describe Homogeneous

A

Move data to destination in same format or same storage engine as the source. All about speed of transfer

EMR

Athena

Amazon RDS

S3

22
Q

Describe Heterogenous

A

Transformed as ingested to the destination storage. Meet the requirements for the correct format.

Redshift

Kinesis

Glue

RDS

S3

23
Q

What is API gateway

A

AWS API Gateway is a fully managed service that allows developers to create, publish, maintain, monitor, and secure APIs at any scale. It serves as a “front door” for applications to access data, business logic, or functionality from your backend services such as AWS Lambda functions, Amazon EC2 instances, or other web services.

24
Q

Cognito

A

Amazon Cognito is a service provided by AWS that enables you to add authentication, authorization, and user management to your web and mobile applications. It simplifies the process of handling user sign-up, sign-in, and access control, allowing developers to focus on building their applications without dealing with complex authentication code.

25
Q

HSM

A

A Hardware Security Module (HSM) is a physical device that provides cryptographic functions to securely generate, store, and manage cryptographic keys. HSMs are designed to protect sensitive data and cryptographic keys from theft and misuse, making them critical components in security-sensitive environments.

26
Q

Batch

A

AWS Batch is a fully managed service that enables developers, scientists, and engineers to efficiently run hundreds of thousands of batch computing jobs on AWS. AWS Batch automatically provisions the optimal quantity and type of compute resources based on the volume and specific resource requirements of the batch jobs submitted.

27
Q

Step Functions

A

AWS Step Functions is a fully managed service that enables you to coordinate distributed applications and microservices using visual workflows. It is particularly useful for creating complex workflows that involve multiple AWS services and automated tasks, providing a way to define and execute tasks in a sequence, parallel, or conditionally based on logical rules.

28
Q

App Sync

A

AWS AppSync is a fully managed service that simplifies application development by enabling developers to create scalable GraphQL APIs. It integrates seamlessly with AWS services, making it easy to build engaging real-time and offline mobile and web applications.

29
Q

Graph QL

A

GraphQL is a query language for APIs and a runtime environment for executing those queries by using a type system you define for your data.

30
Q

Lazy Loading

A

Lazy loading is a design pattern used to defer the loading of resources until they are actually needed. In the context of AWS, lazy loading can be implemented in various services to optimize performance, reduce costs, and improve user experience by minimizing the initial load time and resource usage.
