Persistent block storage for Amazon EC2

Temporary block storage

On premises IT environment integration with cloud storage

large data volume data transfer

Global content delivery can be used to deliver entire website dynamic static streaming and interactive content Using a global network of edge locations.

- Trade capital expense for variable expense - Pay only when you consume resources - Pay only per how much you consume - min / sec / hr / GB /TB

- Benefit from massive economies of scale

- Stop guessing about capacity - scales to business needs - no long term contracts

- scales infinitely with demand - Acloud guru was built in 3 weeks using serverless architecture

- focus on your strengths - let someone else manage infrastructure for you

- go global in minutes - deploy app in multiple regions around the world in a few clicks - lower cost - lower latency - better experience

- I manage the server and OS - Data provider has no access to server

- Someone else manages H/W & S/W - I focus on my app - Someone else manages - security - patching - updates - maintenance

- I manage my inbox - Google takes care of everything else

Available to all

Mixture of public and private

Managed in your data center

Geographical area - 2 or more Availability Zones

Many data centers

CDN Endpoints for Cloudfront Location where content will be cached This is separate from an AWS Region/AZ

- $ 29 / Month - 12 / 24 Hour response

- $100 / month - 24 x 7 access - 1 hour response

- 15K / Month - 15 minute response - Tam

- Console - Command Line - SDK

Email account you used to set up account

- Full Admin Access - Do not give account credentials away - create user for each individual - use MFA to secure root account

- Place to store users that inherit all permissions of the group - developers - sa's - hr

Set up with JSON

Key Value Pairs - { "name" : "MikeMcMac1" } - between the brackets

Place to store objects - directory on a computer accessible from anywhere in the world - console - command line

Each object has a unique name

Files only

S3 is not suitable for installing operating systems

successful S3 uploads result in this status code

Encrypt objects in transit to S3

Encrypt object at REST

Current

Archive 3 - 5 Hour retrieval time

Restrict access to entire bucket you can make entire s3 buckets public

Restrict access to individual objects (files)

Upload files to edge locations and Amazon transfers the files, over there internal network, to buckets.

Globally you can also have buckets in individual regions

Names have to be unique You can not have the same name as someone else

Newly created buckets are private

Replicate the contents on one bucket to another bucket automatically

You can change the storage class and encryption level of your objects on the fly

html

Amazon Resource Name

requiring database connections can not be hosted on S3

orgs may place static websites on S3 when they anticipate large numbers of requests (for instance the Bond movie)

Amazon's -CDN - Content Delivery Network

network (system of distributed servers) that deliver web pages and other web content to a user

Geographic location Origin of the webpage Content delivery server

origin of all the files that the CDN will distribute.

S3 Bucket EC2 Instance Elastic Load Balancer Route 53

Name given to the CDN which consists of a collection of Edge Locations.

for content are automatically routed to the nearest edge location, so content is delivered with the best possible performance

Seamless non-AWS servers that store original, definitive versions of your files.

works with other AWS services - S3 - EC2 - Elastic Load Balancer - Route 53.

Web Distribution - websites RTMP - Used for Media Streaming

Amazon Elastic Cloud Compute

Web service that provides resizable compute capacity in the cloud

reduces time required to obtain and boot new server instances in minutes allowing you to quickly scale capacity up or down as required

Allow you to pay a fixed rate by the hour (or by the second) with no commitment.

Provide you with a capacity reservation, and offers discount on the hourly charge for an instance. 1 Year or 3 Year terms

Apps with flexible start and end times Apps that are only feasible at very low compute prices Users with urgent computing needs for large amounts of additional capacity Pricing moves up and down all the time like the stock market If bid price is exceeded then computing stops Else If bid price is < = spot price THEN computing continues

Physical EC2 server dedicated for your use. reduce costs by allowing you to use your existing server-bound software licenses.

Users that want the low cost and flexibility of Amazon EC2 without any up-front payment or long-term commitment Applications with short term, spiky or unpredictable workloads that cannot be interrupted Applications being developed or tested on Amazon EC2 for the first time.

Applications with steady state or predictable usage Applications that require reserved capacity Users able to make upfront payments to reduce their total computing costs even further Standard RI's (Up to 75% off on demand) Convertible RI's (Up to 54% off on demand) capability to change the attributes of the RI as long as the exchange results in the creation of RI's of => Value Scheduled Ri's available to launch within the time window you reserve. This option allows you to match your capacity reservation to a predictable recurring schedule that only requires a fraction of a day, a week, or a month.

Useful for regulatory requirements that may not support multi-tenant virtualization. Great for licensing which does not support multi-tenacy or cloud deployments. Can be purchased On-Demand (hourly) Can be purchased as a Reservation for up to 70% off the On-Demand price.

If terminated by Amazon EC2 then you are not charged for partial hour usage. If you terminate the instance yourself, you are charged for any hour in which the instance ran.
