23 Three cloud platforms AWS / Google Cloud / Azure

Hello students,
If you are ever asked a question in exam about “Cloud Platform” (not PaaS), remember three cloud platform providers namely AWS, GCP, Azure

In this blog we look at the cloud computing features provided by three cloud providers namely

  • Amazon Web Services (AWS)
  • Google Cloud Platform (GCP)
  • Microsoft Azure Cloud

Amazon Web Services

We look specifically at 13 services provided Amazon Web Services cloud provider

1. Management Console – user interface for customers to use AWS services over the internet

2. Elastic Compute Cloud (EC2) – virtual machine provisioning

3. Internet Users – User access is secured via public key infrastructure and Identity Access Management services

4. Amazon Machine Image (AMI) – linux, windows images are readily available to use and go, with many other complex machine image via AMI services

5. Static Network Addresses – Elastic , public and static IP addresses is available readily for use over the internet

6. Servers – any number of servers are accessible and can be configured for distributed computing

7. Simple DB – a non-SQL database service

8. Elastic Block Storage (EBS) – block storage service

9. Simple Queue Service (SQS) – message queue service

10. Simple Storage Service (S3) - object storage service

11. Auto Scale, Cloud Watch, Elastic Load Balancing – Elastic Scaling and monitoring services

12. Network Security – Firewall Security group, Access Control List services

13. Charges – Pay as you go model service

Google Cloud Platform (GCP)

If AWS is more of a IaaS service, GCP is more of a PaaS service. Google has been using its own platform for years , especially to search or locate anything and now the most powerful platform in the world is provided to everyone via its cloud service.
Google Cloud Platform has a strong platform called Google App Engine which supports programming in multiple languages as well creating web sites. Apart from these it provides the platform that is utilized by its search and youtube platform such as:

1. Google File System (GFS)  - file system used to store and access files such as program code

2. Resource Usage Measurement – App engine measures only CPU time and number of web requests

3. Cost Usage / Charges - Google uses the charges only for execution time. Example I upload a code which occupies 1 MB storage and you run it for 1 hour, it will not charge for storage space but it will charge only for 1 hour usage.

4. Google Web Application Server – Web server services from Google

5. Scheduler – Since all google platform is a shared managed service, users do not choose or own machines, rather they execute jobs, programs, web requests which is scheduled by Google's Scheduler services

6. MemCache – Distributed In-Memory Cache services used by Google platform to enable faster execution for in-numerous customers all over the world

7. Google DataStore – Google's own non-relational database which stores every field and data as kinds and entities (similar to tables and records). It also provides querying services using Google Query Language (GQL)

Microsoft Azure Cloud
Similar to GCP being more of a PaaS service, Azure cloud can also be seen as dominating in .Net based PaaS services. 

It has a managed IIS web server platform service that is utilized to support web application development.

It controls the platform using two types of user roles namely web roles and worker roles.

It has a managed database called SQL Azure which has 10 GB limit. 

Azure provides access to various .Net services for any type of application development.

11 Computing Platforms

Welcome students ! Introduction to Unit 2  In Unit 2, we look at platform architectures that have evolved over time from the days of  earlier main frame architecture into today's cloud service platform architecture. Today we have cloud computing platform which use and provide cloud technologies   ( Parallel Computing, Distributed Computing, Service Oriented     Computing, Virtualization, Web 2.0 (soap, rest, ajax, mashup),  Utility Computing ) cloud delivery services reference model  ( IaaS,PaaS, SaaS ) cloud deployment types  ( Public, Private, Hybrid, Community ) In Unit 1 we already introduced ourselves to cloud technologies such as Parallel Computing, Distributed Computing, Service Oriented Computing and Virtualization.  Just like evolution theory says a monkey became man over many phases, this blog summarizes the Computing Platform architecture for enterprises that has evolved over time in four phases  (computing platform: e...

15 Four layers of Cloud Architecture (Reference Model)

Hello students, In today's blog we look deeper at cloud reference model architecture that generally applies in any cloud environment Any Cloud architecture is based on a four layers of this reference model 1. System Infrastructure 2. Core Middleware 3. User-level Middleware 4. Cloud Applications Each layer is on top of the previous layer System Infrastructure System infrastructure is the most underlying layer in the architecture and it provides physical machines, network, storage needs such as network adapters, routers, SAN disks etc. Core Middleware Core Middleware sits on top of System Infrastructure layer. It provides virtual machines, network virtualization, storage virtualization, hypervisors etc. Both System Infrastructure and Core Middleware essentially provides a way to implement IaaS (Infrastructure as a service) In our assignment, this layer would ideally be Oracle Virtual box User Level Middleware User Level Middleware sits on top of core middleware and provides run-ti...

25 Task Computing : HTC-HPC-MTC

Dear students, In our last blog, we came across concurrent computing, where the focus was how a single program can be computed faster by decomposing either based on data sets (Domain Decomposition) or based on functionality (Function Decomposition). Once the decomposition is planned properly in the program, it can be assigned to multiple cores or multiple threads. Concurrent computing is a form of parallelism on the same machine. When we talk about task computing, we are looking at executing not single program, but multiple programs. Each program can be considered as a task with lot of data or consisting of many work units. These tasks can be executed using multiple machines. Task Computing is a form of parallelism on multiple machines. It is a network of machines, where one machine (called local node) becomes responsible to submit the task, then one machine schedules it , checks status on all submitted tasks (access nodes) , one machine provides any resources such as files, data...
