Most Frequently Asked Amazon interview questions
Elastic Block Storage’s performance varies. It can go above the SLA and after that drop below it. The average disk I/O rate of SLA can frustrate performance experts searching for consistent and reliable disk throughout a server. But, the virtual instances of AWS don’t behave this way.
The EBS volume can be backed up through a graphical user interface such as elasticfox or the snapshot facility of an API call. The performance here can be improved using Linux software raid and striping across the volumes.
As the incoming traffic is distributed optimally across the various AWS instances by an Elastic Load Balancer, a buffer will synchronize the various components and arranges additional elastic to a burst of traffic or load. All the elements are prone to work in an unstable way of request receiving and processing.
The buffer here creates the equilibrium linking various apparatus and eventually crafts them effort at the identical rate to provide more rapid services.
Here are a few crucial facts to consider to secure data while carrying in the cloud.
- While the data is moving from one point to another, no one should seize the information in the cloud.
- There should be no security key from several storerooms in the cloud.
- Use of approved encryption methods for segregation of information from additional companies’ data.
There are a total of three layers of cloud computing, and they are as following, Software as a Service - SaaS, Infrastructure as a Service - IaaS, and Platform as a Service - PaaS
To use a classic link, the users have to enable minimum one virtual private cloud on their account for the traditional connection. Later, they can associate a security group from that virtual private cloud to the EC2 classic instance that they would prefer.
This process will make sure that the EC2 classic instance is linked to VPC and will become s member of the selected security group of the VPC. The EC2 classic instant cannot be connected to more than one VPC at the same time.
It’s not possible for an EC2 classic instance to be a member of virtual private cloud, but it can become a member of the security group of that VPC. The security group must be associated with the EC2 classic instance.
It’s possible for an elastic network interface to host multiple websites with separate IP addresses, but not the best suited to prefer in the case of multiple interfaces. It will be logical to assign additional private IP addresses to the instance and to associate the flexible network interfaces to the private IPs as per the requirement.
No, the virtual private cloud peering the traffic within the region is not encrypted, though the traffic between the instances present in peered VPCs does remain private and isolate. The same process goes to the fact that the transportation between in a single VOC between two instances are also individual and isolated.

In peered VPCs and between instances in the VPC, there is absolutely no difference in bandwidth between instances. The peered VPCs can be spanned by a placement group. But, the user will not be provided with full bisects on bandwidth which is present between the instances in peered VPCs.
Yes, it’s possible to modify the VPC’s route table. Users are allowed to create route rules to specify which subnets are to be routed to VPC or any other instances.
