      Amazon EC2 (Elastic Compute Cloud) 是一个让用户可以租用云电脑运行所需应用的系统。EC2借由提供web服务的方式让用户可以弹性地运行自己的Amazon机器镜像文件,用户将可以在这个虚拟机上运行任何自己想要的软件应用程序
      用户可以随时创建、运行、终止自己的虚拟服务器,使用多少时间算多少钱,也因此这个系统是"弹性"使用的。EC2让用户可以控制运行虚拟服务器的主机地理位置,这可以让延迟还有备援性最高。例如,为了让系统维护时间最短,用户可以在每个时区都运行自己的虚拟服务器。Amazon以Amazon Web Services (AWS)的品牌提供EC2的服务。

            历史  

             Amazon在2006年8月25日发布EC2受限公众Beta版本

         虚拟机  

            EC2使用Xen虚拟化技术。每个虚拟机,又称作实例,能够运行小、大、极大三种能力的虚拟私有服务器。Amazon利用EC2 Compute Units去分配硬件资源。EC2系统提供以下的虚拟机实例类型

        小型实例

      默认配置了1.7 GB的存储器,一个虚拟核心上运行一个EC2 Compute Unit,160GB的硬盘空间, 32位平台

        大型实例

      默认配置了7.5GB的存储器,两个虚拟核心上各运行两个EC2 Compute Units,850GB的硬盘空间, 64位平台

        极大实例

      默认配置了15GB的存储器,四个虚拟核心上各运行两个EC2 Compute Units,1690GB的硬盘空间, 64位平台

          

        自动配置  

            Amazon EC2自动配置容量的功能允许用户自动调整Amazon EC2的容量。假如用户的流量达到尖峰,自动配置功能可以自动增加更多的容量至虚拟主机上以维持性能。

    Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides secure, resizable compute capacity in the cloud. It is designed to make web-scale computing easier for developers. The ...

    Overview

    • Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides secure, resizable compute capacity in the cloud. 
    • The simple web interface of Amazon EC2 allows you to obtain and confifigure capacity with minimal friction.
    • Amazon EC2 reduces the time required to obtain and boot new server instances (called Amazon EC2 instances) to minutes, allowing you to quickly scale capacity, both up and down, as your computing requirements change.

    EC2 Features

    • Virtual computing environments, known as EC2 instances
    • Preconfigured templates for your instances, known as Amazon Machine Images (AMIs), that package the bits you need for your server (including the operating system and additional software)
    • Various configurations of CPU, memory, storage, and networking capacity for your instances, known as Instance types
    • Secure login information for your instances using key pairs (AWS stores the public key, and you store the private key in a secure place)
    • Storage volumes for temporary data that’s deleted when you stop or terminate your instance, known as Instance store volumes
    • Persistent storage volumes for your data using Amazon Elastic Block Store (Amazon EBS), known as Amazon EBS volumes
    • Multiple physical locations for your resources, such as instances and EBS volumes, known as Regions and Availability Zones
    • A firewall that enables you to specify the protocols, ports, and source IP ranges that can reach your instances using security groups
    • Static IP addresses for dynamic cloud computing, known as Elastic IP addresses
    • Metadata, known as tags, can be created and assigned to EC2 resources
    • Script virtual hardware management with User Data
    • Use Enhanced Networking for more Packets Per Second (PPS), lower latency, and less jitter
    • Placement Groups provides low-latency networking between all instances in the cluster
    • Better IOPS with EBS-optimized instances
    • Dedicated Host for security and complicance
    • Virtual networks you can create that are logically isolated from the rest of the AWS Cloud, and that you can optionally connect to your own network, known as virtual private clouds (VPCs)

    How to lunch an EC2 instance

    1. Select a pre-configured, templated Amazon Machine Image (AMI) to get up and running immediately. Or create an AMI containing your applications, libraries, data, and associated configuration settings.
    2. Configure security and network access on your Amazon EC2 instance.
    3. Choose which instance type(s) you want, then start, terminate, and monitor as many instances of your AMI as needed, using the web service APIs or the variety of management tools provided.
    4. Determine whether you want to run in multiple locations, utilize static IP endpoints, or attach persistent block storage to your instances.
    5. Pay only for the resources that you actually consume, like instance-hours or data transfer.

    Compute Basics

    There are two concepts that are key to launching instances on AWS:
    • Instance type: the amount of virtual hardware dedicated to the instance
    • AMI: the software loaded on the instance
     

    Detail Reading

    Exam Essentials

    Know the basics of launching an Amazon ec2 instance.
    To launch an instance, you must specify:
    • an AMI, which defines the software on the instance at launch,
    • an instance type, which defines the virtual hardware supporting the instance (memory, vCPUs, and so on).

    Understand how to provision and launch an EC2 instance.

    • select the right AMI and instance type
    • configure a security group,
    • add any extra storage volumes that might be needed,
    • point to any necessary user data and scripts,
    • tag all the elements using descriptive key values.
    Know how security groups protect instances
    • Security groups are virtual firewalls controlling traffic in and out of your Amazon EC2 instances.
    • They are deny by default, and you can allow traffic by adding rules specifying traffic direction, port, protocol, and destination address (via Classless Inter-Domain Routing [CIDR] block).
    • They are applied at the instance level, meaning that traffic between instances in the same security group must adhere to the rules of that security group.
    • They are stateful, meaning that an outgoing rule will allow the response without a correlating incoming rule.
    Know how to interpret the effect of security groups
    • When an instance is a member of multiple security groups, the effect is a union of all the rules in all the groups. 
    Know how to securely access your instances running on the cloud
    • Security Groups and Network Access Lists
    • Access Management (IAM) roles
    • network address translation (NAT) instances
    • key pair at first start
    Know How to change the capabilities of an existing instance
    1. Stop instance
    2. Change instance type
    3. Start instance
    Know what architectures are suited for what Amazon ec2 pricing options
    • Spot Instances are best suited for workloads that can accommodate interruption.
    • Reserved Instances are best for consistent, long-term compute needs.
    • On-Demand Instances provide flexible compute to respond to scaling needs.
    Know how to combine multiple pricing options that result in cost optimization and scalability.
    • On-Demand Instances can be used to scale up a web application running on Reserved Instances in response to a temporary traffic spike.
    • For a workload with several Reserved Instances reading from a queue, it’s possible to use Spot Instances to alleviate heavy traffic in a cost-effective way.
    • These are just two of countless examples where a workload may use different pricing options.
    Know the benefits of enhanced networking.
    • Enhanced networking enables you to get significantly higher PPS performance, lower network jitter, and lower latencies.
    Know the capabilities of vm import/export.
    • VM Import/Export allows you to import existing VMs to AWS as Amazon EC2 instances or AMIs.
    • Amazon EC2 instances that were imported through VM Import/Export can also be exported back to a virtual environment.
    Know the methods for accessing an instance over the internet.
    • You can access an Amazon EC2 instance over the web via public IP address, elastic IP address, or public DNS name.
    • There are additional ways to access an instance within an Amazon VPC, including private IP addresses and ENIs.
    Know the properties of the Amazon EC2 pricing options.
    • On-Demand Instances require no up-front commitment, can be launched any time, and are billed by the hour.
    • Reserved Instances require an up-front commitment and vary in cost depending on whether they are paid all up front, partially up front, or not up front.
    • Spot Instances are launched when your bid price exceeds the current spot price. Spot Instances will run until the spot price exceeds your bid price, in which case the instance will get a two-minute warning and terminate.
    Know what determines network performance.
    • Every instance type is rated for low, moderate, high, or 10 Gbps network performance, with larger instance types generally having higher ratings.
    • Additionally, some instance types offer enhanced networking, which provides additional improvement in network performance.
    Know what instance metadata is and how it’s obtained.
    • Metadata is information about an Amazon EC2 instance, such as instance ID, instance type, and security groups, that is available from within the instance.
    • It can be obtained through an HTTP call to a specific IP address:http://169.254.169.254/latest/meta-data/
    Know how to Create and Launch an AMI Based on an Existing Instance Storage Volume
    1. Create an image from the instance’s volume (you’ll access the dialog through the Actions pull-down menu in the Instances Dashboard).
    2. Launch an instance from the console and select the new AMI from the My AMIs tab.

    • [讲师]欢迎回来。
      在这个视频中,我们将从一个新的概念开始。
      我们将谈论Elastic Load Balancers。
      如果您已经在IT行业工作了一段时间,或者您有机会使用网络设备,那么您很可能已经体验过负载均衡器,或者至少您已经听说过它们。
      现在,我们将从AWS的角度来看一下负载均衡器。
      让我们开始。
      什么是Elastic Load Balancing?
      好吧,Elastic Load Balancing在多个EC2实例之间分配传入的应用程序流量,最好是在多个可用区中。
      增加应用程序的容错能力。
      负载均衡器可作为客户端的单一联系点,从而提高应用程序的可用性。
      此外,负载均衡器还可以防止您的EC2实例或您的服务器暴露在互联网上,因为您的实例将位于负载均衡器后面,而且是负载平衡器,它 会暴露在互联网上。
      我们可以根据需求的变化在负载均衡器中添加或删除实例,而不会中断对应用程序的整体请求流。
      Elastic Load Balancing还会随着应用程序流量的变化而扩展负载均衡器,并可自动扩展到绝大多数工作负载。
      我们还可以配置运行状况检查,这些检查用于监视已注册实例的运行状况,以便负载均衡器可以仅向健康实例发送请求。
      当流量在实例之间分配时,假设其中一个实例发生故障,或者该实例可能出现问题。
      我们不想将流量发送到不健康的实例,因此负载平衡器具有健康监控功能。
      他们不断检查位于其后面的实例的运行状况,如果发现其中一个实例不健康,则不会将流量转发到该实例。
      负载平衡器还可用于卸载加密和解密工作,以便您的实例可以专注于其主要工作,即为流量提供服务。
      如果您从未听说过SSL卸载,那么您可以通过这种方式拦截SSL流量并引导该流量的内容。
      如果我们将Elastic Load Balancers配置为这样做,它们甚至可以做到这一点。
      好的,现在我有一个图表来向您展示负载均衡器如何对流量进行负载均衡。
      这是一个负载均衡器,我们有三个EC2实例位于负载均衡器后面。
      当第一个请求进入时,它将被发送到第一个实例。
      当第二个请求进入时,它进入第二个实例,当第三个进入时,它进入第三个实例。
      然后重复该循环。
      同样,它是第一个实例,第二个实例和第三个实例。
      现在,让我们假设一段时间后,第三个实例会产生一些问题,并将其归类为不健康。
      如果发生这种情况,流量现在将在实例1和实例2之间分配,如图所示。
      那么,这是Elastic Load Balancing的高级概述。
      在下一个视频中,我们将深入研究一种称为经典负载均衡器的特定类型的负载均衡器。
      我要感谢你的观看,我会在下一个视频中看到你。
      谢谢。
