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…

Cloud integration two top key methods people follow

ITaaS is the most recent entrant to the IT landscape. It is an efficient delivery method. With the meteoric and mesmerizing rise of service orientation principles, every single IT element is being viewed and visualized as a service that sets the tone for the service era.

Two top methods for Cloud integration

1 - Integration as a service (IaaS)

  1. It is a budding and distinctive capability of clouds that help in fulfilling internal as well as external business integration requirements. Increasingly, business applications are deployed in clouds to reap the manifold business and technical benefits of using clouds.
  2. On the other hand, innumerable mission-critical applications and data sources still remain locally stationed and sustained primarily due to the expressed security concerns associated with hosting them in clouds. The question here is how to create seamless data flow between hosted and on-premise applications so that they work together.
  3. The IaaS overcomes these challenges by smartly utilizing the time-tested B2B integration technology as the value-added bridge between SaaS solutions and in-house business applications. The B2B systems are capable of driving this new on-demand integration model because they are traditionally used to automate business processes between manufacturers and their trading partners.
  4. This means they provide application-to-application connectivity along with the functionality that is crucial for linking internal and external software securely. 
  5. Unlike the conventional EAI solutions designed only for internal data sharing, B2B platforms have the ability to encrypt files for safe passage across the public network, manage large data volumes, transfer batch files, convert disparate file formats, and guarantee data delivery across multiple enterprises. 
  6. The IaaS just imitates this established communication and collaboration model to create reliable and durable linkage for ensuring smooth data passage between traditional and cloud systems over the web infrastructure.

2 - Hub-and-spoke architecture

  • It further simplifies the implementation and avoids placing an excessive processing burden on the customer side. The hub is installed at the SaaS provider's cloud center to do the heavy lifting, such as the reformatting of files.
  • A spoke unit at each user site typically acts as a basic data transfer utility. With these pieces in place, SaaS providers can offer integration services under the same subscription/ usage-based pricing model as their core offerings. 
  • As IT resources are becoming more distributed and decentralized every day, linking and leveraging them for multiple purposes need a multifaceted infrastructure.
  • Clouds, being web-based infrastructures, are the best fit for hosting scores of unified and utility-like platforms to take care of all sorts of brokering needs among connected ICT systems.
