14. Video Streaming via AWS S3
● Why stream video?
● Solution overview
● Video playback
● Configure your buckets
● Use the API
● Upload

15. Why stream video?
15
The Scenario
● Job applicants upload videos
● Videos are only available to intended
recipients
● The first frame is displayed before playback
● Playback can start immediately

16. 16
Solution Options
Static videos
● OutSystems resources
● Poor app performance

18. Video Playback
18
● Video player control
● Temporary URL
● Caching the URL
● AWS CORS configuration
● Consider using a CDN (we didn’t need one)
● Transcoding with MediaConvert

19. Configure your
buckets
19

20. AWS S3 Configuration
20
For each environment
● Create API user accounts
● Record “secret” and “access” keys
● Access type “Programmatic access - with an access key”
● Create S3 buckets (in the correct AWS region)

21. S3 Bucket Policy
21
● Ensure bucket public access is off (the default)
● Give access to the API user with a bucket policy
"Statement": [
{
"Sid": "Stmt999999999999",
"Effect": "Allow",
"Principal": {
"AWS": "arn:aws:iam::99999999999:user/myproj-dev-api"
},
"Action": "s3:*",
"Resource": "arn:aws:s3:::myproj-dev/*"
} ]
…

22. CORS Configuration
22
[ {
"AllowedHeaders": [ … ],
"AllowedMethods": [ "GET" ],
"AllowedOrigins": [ "https://YOUR_DOMAIN.com" ],
"ExposeHeaders": [ … ],
"MaxAgeSeconds": 3000
} ]
● Set “Allowed Origins” to your application URL

23. Use the API
23

24. Connecting to AWS S3
24
● AWS S3 API
● To connect, you will need:
○ AWS Access Key
○ AWS Secret Key
○ AWS Region Name
○ AWS Bucket Name

25. Get Temporary URL
25
● AmazonS3Client.GetPreSignedURL
Expires = DateTime.UtcNow.AddMinutes(durationMins)
● Cached server action
● Cache time should be less than the URL timeout

26. Upload
26

27. Uploading files
27
Upload the whole file with
● Store file metadata
● TransferUtilityUploadRequest.Upload
● Generate the File “Key” (Not the filename!)
● Create a pseudo path with <ENTITY>/<ID>/<KEY>
eg CUSTOMER/123/abcd-1234-cbad.mpg

28. Uploading large files
28
Upload in chunks
● AmazonS3Client.InitiateMultipartUpload
● AmazonS3Client.UploadPart
● AmazonS3Client.CompleteMultipartUpload
● Custom client-side upload widget to chunk the file

AWS
Certifications
and
Pathways

34. The AWS Certified Cloud Practitioner (CCP) is the easiest Amazon Web Services certification. It’s a cloud beginner-friendly
certification that covers the basics of AWS and the cloud and requires no technical experience as a prerequisite. Though,
unless you have some experience with AWS, you’ll still need to study to ace it. (It’s not that easy.)
It covers around 56 AWS services, almost 25% of the AWS Universe.
It’s probably for you if: You need to know foundational cloud concepts — like what is cloud, what is cloud migration, and how
does AWS works at a high level — but won’t be getting your hands dirty with implementation.
AWS Cloud Practitioner
34
● Prerequisites: None
● Recommended Experience: 6 months of AWS and industry knowledge
● Skills covered:
○ Basic AWS architectural foundations
○ Key AWS services
○ AWS security and compliance

35. AWS Solution Architect
The AWS Certified Solutions Architect – Associate certification gives you a broad overview of AWS, and forms a valuable foundation on
which you can build everything else you’ll learn moving forward. There’s a reason it’s been the #1 cloud certification for years running.
The CSA – Associate certification focuses on the core AWS services, like Identity and Access Management (IAM), Virtual Private Cloud
(VPC), S3, and EC2. Studying these core services will give you a good understanding of how AWS approaches security, networking, data
storage, and compute capability.
It’s probably for you if: If you’re going to be working in AWS in any hands-on capacity, the Associate-level certifications should mark the
point where your journey truly begins. The AWS Cloud Practitioner provides a solid conceptual footing, but the AWS Associate-level
certifications are where the rubber really meets the road in terms of day-to-day implementation.
35
● Recommended Experience: One year of experience working in AWS to solve problems and implement solutions.
● Skills covered:
○ How AWS-based applications work
○ Building secure applications on AWS platform
○ Deploying hybrid AWS systems
○ Hands-on AWS application design
○ AWS application development
○ Security in AWS environments
