What Is Cloud Computing

Cloud computing provides access to IT resources such as computing power, applications, and storage to users as per their demands. Here, users do not need to maintain their physical resources on their premises. In cloud computing, you can pay only for the resources you have used, so there are no investment costs. This service provides greater flexibility and scaling on resources according to your changing workloads.

Can S3 Be Used With Ec2 Instances If Yes How

Yes, it can be used for instances with root devices backed by local instance storage. By using Amazon S3, developers have access to the same highly scalable, reliable, fast, inexpensive data storage infrastructure that Amazon uses to run its own global network of web sites. In order to execute systems in the Amazon EC2 environment, developers use the tools provided to load their Amazon Machine Images into Amazon S3 and to move them between Amazon S3 and Amazon EC2.

Another use case could be for websites hosted on EC2 to load their static content from S3.

For a detailed discussion on S3, please refer our S3 AWS blog.

Explain What T2 Instances Are

The T2 Instances are intended to give the ability to burst to a higher performance whenever the workload demands it and also provide a moderate baseline performance to the CPU.

The T2 instances are General Purpose instance types and are low in cost as well. They are usually used wherever workloads do not consistently or often use the CPU.

Success And Scale Bring Broad Responsibility

We started in a garage, but we’re not there anymore. We are big, we impact the world, and we are far from perfect. We must be humble and thoughtful about even the secondary effects of our actions. Our local communities, planet, and future generations need us to be better every day. We must begin each day with a determination to make better, do better, and be better for our customers, our employees, our partners, and the world at large. And we must end every day knowing we can do even more tomorrow. Leaders create more than they consume and always leave things better than how they found them.

Practice questions:

As one of the world’s largest companies, Amazon has a responsibility to its employees, shareholders, and the planet. That’s why sustainability and social responsibility are core values at Amazon, even if customer obsession seems to dominate the conversation.

The company strives to make sure its operations have a positive impact on the environment and that employees work hard to create a workplace where everyone can thrive. They understand that Amazon’s size and reach gives a unique opportunity to make a difference in the world.

Which Type Of Scaling Would You Recommend For Rds And Why

There are two types of scaling – vertical scaling and horizontal scaling. Vertical scaling lets you vertically scale up your master database with the press of a button. A database can only be scaled vertically, and there are 18 different instances in which you can resize the RDS. On the other hand, horizontal scaling is good for replicas. These are read-only replicas that can only be done through Amazon Aurora.

When You Need To Move Data Over Long Distances Using The Internet For Instance Across Countries Or Continents To Your Amazon S3 Bucket Which Method Or Service Will You Use

  • Amazon Snowball
  • Answer C.

    What Role Does Buffer Play In Amazon Web Services

    The buffer is responsible for handling incoming traffic while seamlessly integrating the various components in the AWS cloud platform. The components are liable to acquire and process requests in an insecure manner. A buffer establishes a balance that unites multiple devices and generates the effort simultaneously, allowing for faster service delivery. It’s simple to balance the incoming traffic and pipeline usage using a buffer, ensuring consistent packet delivery across the cloud platform in all circumstances.

    What Are Some Of The Security Best Practices For Amazon Ec2

    How Will You Use The Processor State Control Feature Available On The C48xlarge Instance

    The processor state control has 2 states, namely:

    • The C State: Represents the sleep state. Varies from c0 to c6, where c6 is the deepest sleep state for a processor.
    • The P State: Represents the performance state. Varies from p0 to p15, where p15 is the lowest possible frequency.

    A processor has multiple cores, and each of them requires thermal headroom for gaining a boost in performance. Hence, the temperature needs to be kept at an optimal level so that the cores can perform at their highest.

    When a core is put into the sleep state then it results in a reduction of the overall temperature of the processor. This gives an opportunity to other cores for giving out a better performance. Hence, a strategy can be devised by properly putting some cores to sleep and others in a performance state to get an overall performance boost from the processor.

    Instances like the c4.8xlarge allow customizing the C and P states for customizing the processor performance according to the workload.

    To Deploy A 4 Node Cluster Of Hadoop In Aws Which Instance Type Can Be Used

    unnamed file 3

    First lets understand what actually happens in a Hadoop cluster, the Hadoop cluster follows a master slave concept. The master machine processes all the data, slave machines store the data and act as data nodes. Since all the storage happens at the slave, a higher capacity hard disk would be recommended and since master does all the processing, a higher RAM and a much better CPU is required. Therefore, you can select the configuration of your machine depending on your workload. For e.g. In this case c4.8xlarge will be preferred for master machine whereas for slave machine we can select i2.large instance. If you dont want to deal with configuring your instance and installing hadoop cluster manually, you can straight away launch an Amazon EMR instance which automatically configures the servers for you. You dump your data to be processed in S3, EMR picks it from there, processes it, and dumps it back into S3.

    What Are The Pricing Models For Ec2 Instances

    There are four pricing models for EC2 instances:

    • On-Demand instance
    • On-Demand pricing is also known as pay-as-you-go. Pay-as-you-go is a pricing model that allows you to pay only for those resources that you use.
    • You need to pay for the compute capacity by per hour or per second that depends on which instances you run.
    • On-Demand instance does not require any upfront payments.
    • While using On-Demand instance, you can increase or decrease the compute capacity based on the requirements of your application.
    • On-Demand instances are recommended for those applications which are of short term and unpredictable workloads.
    • Users that want low cost and flexibility on EC2 instances with no upfront payments.
    • On-Demand instances are used for those applications which have been developed or tested on EC2 for the first time.
  • Reserved instance
  • Reserved instance is the second most important pricing model that reduces the overall cost of your AWS environment by making an upfront payment for those services that you know will be used in the future.
  • Reserved instances provide a discount of up to 75% as compared to On-Demand instance.
  • Reserved instances are assigned to a specific Availability zone that reserves the compute capacity for you so that you can use whenever you need.
  • Reserved instances are mainly recommended for those applications that have steady state and require reserve capacity.
  • Spot instances consist of unused capacity which is available at a highly discounted rate.
