Meet AWS Kinesis

December 8, 2017 at 7:58 pm


In an earlier AWS post here at the blog – I reviewed the core services of AWS with you. This post hits one of the “strays”. While we do not consider Kinesis a core service, it is one you can expect to see pop its head up in the various AWS Certifications.

If the service is brought up generically – it references the AWS capability of collecting, processing, and analyzing video and data streams in real time. But in your exam environment, there is a very good chance they are going to be more precise and granular with the exact variation of Kinesis you must identify. Here they are:

  • Amazon Kinesis Video Streams – your cameras can stream video securely to AWS Kinesis using the appropriate Kinesis SDK. AWS then stores, encrypts and indexes the video for your eventual analysis. A Kinesis API permits the easy retrieval of video fragments you might need.

  • Amazon Kinesis Data Firehose – allows the acceptance of data streams (at a high rate). Kinesis then stores the data in S3 or Redshift or another AWS storage vehicle. The data can then be accessed for analysis directly from AWS.

  • Amazon Kinesis Data Streams – takes in and stores data streams for your business analysis tools.

  • Amazon Kinesis Data Analytics – you capture the data using Data Firehouse or Data Streams. AWS then runs standard SQL against the data and sends the results to your business analytics tools.

What are the benefits of Amazon Kinesis? First of all – speed! Data analysis can be performed in nearly real-time from the including streams. Second, AWS handles the complex text of stream management applications for you. Finally, AWS provides a fully scalable solution, permitting even hundreds of thousands of simultaneous sources.

So there you have it! While you will not face many Kinesis questions in your AWS exams, you will certainly face some! Thank you for reading.

Identifying the AWS Core Services!

December 3, 2017 at 2:20 pm


If you are preparing for literally any level of AWS Certification, I think an excellent first step is to identify what I term core services. These services make the foundataion of AWS and they are ALWAYS the most tested areas.

I cover these services in depth in the growing list of AWS courses at CBT Nuggets! 

To simplify your locating them – I will group them just as AWS does in the main service list in your Web console.

AWS Compute

  • EC2 – Elastic Compute Cloud allows you to easily scale virtual machines for your main compute horsepower; note that an opposite approach in AWS is serverless compute with Lambda

AWS Storage

  • S3 – Simple Storage Services is object-based, key/value storage for many purposes in AWS
  • EBS – Elastic Block Store permits the use of MDD or SDD storage for many purposes, including boot volumes for EC2 instances

AWS Database

  • RDS – Relational Database Service allows you to host many database types in the cloud; this includes Oracle, MS SQL Server, and even Amazon’s own Aurora
  • DynamoDB – a NoSQL database option in the cloud that performs blazing performance and on-demand scalability
  • ElastiCache – creates in-memory caches for impressive performance interaction; this service also supports open standards in caching

AWS Networking

  • VPC – Virtual Private Cloud provides the networking components needed for an infrastructure including subsets, gateways, routing tables, and security mechanisms

AWS Management

  • CloudWatch – Permits the monitoring of key services; uses metrics and alarms for a familiar monitoring approach
  • CloudTrail – Permits the tracking of potentially all the API calls to AWS; this allows you detailed analysis of all events no matter the source – Web Console, CLI, SDK, etc.

AWS Security

  • IAM – Identity and Access Management allows the creation of users, groups, and roles for interacting securely with AWS

AWS Application Integration

  • SNS – the Simple Notification Service allows the generation of email and text notifications based on AWS events
  • SQS – the Simple Queue Service assists you in decoupling components and queuing messages between these components; this service helps the use of micro services for your processing needs
