4 Layers of AWS Architecture a Quick Answer

I have collected real interview questions on AWS key architecture components. Those are S3, EC2, SQS, and SimpleDB. AWS is one of the most popular skills in the area of Cloud computing. Many companies are recruiting software developers to work on cloud computing.

AWS Key Architecture Components AWS is the top cloud platform. The knowledge of this helpful to learn other cloud platforms. Below are the questions asked in interviews recently.
What are the components involved in AWS?Amazon S3.With this, one can retrieve the key information which is occupied in creating cloud structural design, and the amount of produced information also can be stored in this component that is the consequence of the key specified.Amazon EC2. Helpful to run a large distributed system on the Hadoop cluster. Automatic parallelization and job scheduling can be achieved by this component.Amazon SQS. This component acts as a mediator between different controllers. Also worn for cushioning requirements those are obt…

Internet Of Things Basics (Part-1)

IBM investing $3 billion dollars on internet of things(IOT). What is IOT -It estimates that 90 per cent of all data generated by devices like smartphones, tablets, connected vehicles and appliances is never analysed or acted on.

IoT Basics to Read Now

In simple terms, it means machine-to-machine connecting. The emergence of the Internet of Things (IoT) destroys every precedent and preconceived notion of network architecture. To date, networks have been invented by engineers skilled in protocols and routing theory.

But the architecture of the Internet of Things will rely much more upon lessons derived from nature than traditional (and ossified, in my opinion) networking schemes.

It will consider the reasons why the architecture for the Internet of Things must incorporate a fundamentally different architecture from the traditional Internet, explore the technical and economic foundations of this new architecture, and finally begin to outline a solution to the problem.

Why internet of things require new solution


The architecture of the original Internet was created long before communicating with billions of very simple devices such as sensors and appliances was ever envisioned.

The coming explosion of these much simpler devices creates tremendous challenges for the current networking paradigm in terms of the number of devices, unprecedented demands for low-cost connectivity, and impossibility of managing far-flung and diverse equipment.

Although these challenges are becoming evident now, they will pose a greater, more severe problem as this revolution accelerates.

New generation devices

  1. But the vast majority of devices to be connected in the coming IoT are very different. They will be moisture sensors, valve controls, "smart dust," parking meters, home appliances, and so on. These types of end devices almost never contain the processors, memory, hard drives, and other features needed to run a protocol stack.
  2. These components are not necessary for the end devices' prime function, and the costs of provisioning them with these features would be prohibitive, or at least high enough to exclude wide use of many applications that could otherwise be well served. So these simpler devices are very much "on their own" at the frontier of the network.
  3. How things are connected: Billions of devices worldwide will form a network unprecedented in history. Devices as varied as soil moisture sensors, street lights, diesel generators, video surveillance systems—even the legendary Internet-enabled toasters—will all be connected in one fashion or another.
