In this blog, I will share some quick tips, including Q&A and useful links from Day 4 of AWS Solution Architect Associate covering Module 3: Object Storage Options.
We also covered hands-on Lab 9, Lab 10, and Lab 11 out of our 30+ extensive labs.
The previous week, In Day 3 session, we covered topics Identity & Access Management (IAM), AWS WAF, AWS Shield, and AWS Key Management Service (KMS).
Two weeks before, In Day 2 session, we covered topics Create EC2 Windows Machine, Linux Machine, and Webserver.
Three weeks before, In the Day 1 session, we covered the topics Cloud Service Model, AWS Services, Creating FREE Tier Accounts, and Ways to Access Services.
AWS Storage
Because of its scalability, data availability, security, and performance, Amazon Simple Storage Service (Amazon S3) is the most widely used object storage service and is used by most companies, from startups to enterprise-level. Any data stored over S3 is protected, secure, and always available regardless of the amount of data for a variety of use cases, such as websites, mobile applications that generate lots of data, backups for applications, IoT devices, and big data analytics.

CloudFront
Amazon CloudFront is a content delivery network operated by Amazon Web Services. Content delivery networks provide a globally distributed network of proxy servers that cache content, such as web videos or other bulky media, more locally to consumers, thus improving access speed for downloading the content.
Q5. What is the main benefit of CloudFront?
Ans. By using Amazon CloudFront, the volume of application origin requests is automatically reduced. Content is stored in CloudFront’s edge, and regional caches and only fetched from origins when needed. The load on application origins can further reduce by using Origin Shield to enable a centralized caching layer.
Q6. What is CloudFront origin?
Ans. An origin is a location where content is stored and from which CloudFront gets content to serve viewers. To specify an origin: Use S3OriginConfig to specify an Amazon S3 bucket that is not configured with static website hosting. Any other HTTP server running on an Amazon EC2 instance or any other kind of host.
Q7. Is CloudFront region-specific?
Ans. Amazon CloudFront uses a global network of edge locations and regional edge caches for content delivery. You can see a full list of Amazon CloudFront locations here.

AWS Snowball
AWS Snowball is a service that provides secure, rugged devices, so you can bring AWS computing and storage capabilities to your edge environments and transfer data into and out of AWS. These rugged devices are commonly referred to as AWS Snowball or AWS Snowball Edge devices.
Q8. What is the difference between AWS Snowball and Snowmobile?
Ans. AWS Snowball is a suitcase-sized data migration and edge computing device with two device options: Compute Optimized and Storage Optimized. AWS Snowmobile is a shipping container moved with a tractor-trailer.
Q9. How big is an Amazon snowball?
Ans. In the US regions, Snowballs come in two sizes: 50 TB and 80 TB. All other regions have the 80 TB Snowballs only. If you’re using Snowball to import data, and you need to transfer more data than will fit on a single Snowball, create additional jobs.

AWS Storage Gateway
AWS Storage Gateway is a hybrid cloud service set that gives you on-premises access to virtually unlimited cloud storage. Customers use Storage Gateway to integrate AWS Cloud storage with existing on-site workloads to simplify storage management and reduce costs for key hybrid cloud storage use cases.
Q10. What is the main use case of AWS Storage Gateway?
Ans. The gateway connects your applications to AWS storage by providing standard storage interfaces. It provides transparent caching, efficient data transfer, and integration with AWS monitoring and security services.
Q11. What are the different types of storage gateway?
Ans. There are three types of Storage Gateways:
- File Gateway
- Volume Gateway
- Tape Gateway
Q12. What is the distinction between an S3 file gateway and a storage gateway?
Ans. AWS S3 functions as a file system. It serves as a network disc. If you are unfamiliar with the cloud, you can treat it similarly to Dropbox. AWS Storage Gateway is a virtual interface that allows you to read and write data from and to Amazon S3 and other AWS storage services.
