In this video,
we will provide an overview of Amazon. Easy to.
We will introduce Amazon machine images.
We will explore the different instance types,
and we will explore the concept of elastic block storage.
In our last video,
we created a static history website.
In this video, we will provide an overview of Amazon Easy to.
So what is Amazon easy to, and what does it do for us?
Elastic Compute Clout Easy to
provides us with scalable computing capacity
in the Amazon Web service is clout.
An e C. Two instance
helps to eliminate the requirement for us to spend money on hardware of front.
This enables us to launch as many virtual servers as required for our purposes.
We would also be able to configure networking
and manage our storage needs
E. C. To also enables us to handle changes in requirements by scaling up or down.
This greatly reduces the need
for us to become expert forecasters.
So what are some of the features of e. C two
E. C. To consist of virtual computing environments called Instances,
an Amazon machine image? Or am I
our pre configured templates? For our instances,
the A. M I will pre package the basic image that we will need for our server,
including the operating system
and additional software.
It will also contain various configurations from memory,
and storage capacity. For our instances,
these are known as instance types.
We can also provide secure log in information, for instance, is using key pairs
A W S stores, the public key,
and we store the private key in a secure location.
We can create storage volumes for temporary data
that's deleted when we stop or terminate our instance
these air known as instant store volumes
for persistent storage vibes. For our data,
we can use Amazon Elastic Block Store or Amazon. EBS
A. W S provides multiple physical locations for our instances and Amazon E. B s volumes.
These are called regions and availability zones.
We can launch different types of instances from a single AM I.
An instance type will determine the hardware of the host computer used for our instance.
Each instance type will offer various compute and memory capabilities.
We choose an instance type based on the amount of memory and computing power that we will need
for the application or software that were planning to run
instance. Types fall into the following broad categories.
Amazon. Easy to
a one Instances
these air used for cost savings
for scaling out
arm based applications such as Web servers,
Containerized Micro Service's think like docker
and distributed data stores.
These are optimized for compute intensive workloads.
This includes workloads such as high performance Web servers,
high performance computing,
highly scalable multi player gaming.
deep learning. Inference.
These instance. Types are well suited for memory intensive applications, such as high performance databases.
Distributed Web scale in memory caches,
midsize in memory databases
in real time, Big Data Analytics
These are commonly used for machine learning.
H One instances would feature up to 16 terabytes of H D D based local storage.
It will deliver Hai Dous throughput
and have a balance of compute and memory.
Amazon easy to pricing.
So as we know
Amazon, easy to is free to try for year by the free tier.
There are four ways to pay for Amazon. Easy two instances, though
these are on demand.
and we can also pay for dedicated hosts,
which provide us, with easy to instance, capacity
on physical servers dedicated just for our use.
So on demand,
with on demand instances, we pay for compute capacity per hour
or per second,
depending on which instances that we'd run.
There aren't any long term commitments or up front payments required.
We can increase or decrease our compute capacity
depending on the demands of our application.
provide us with a discount of up to 75%
compared to the on demand. Instance pricing.
when reserved instances are assigned to a specific availability zone,
they provide us with a capacity reservation.
Amazon. Easy to spot instances Allow us to request spare Amazon easy to computing capacity
for up to 90% off of the on demand price.
Now spot instances are really just recommended for
applications that have flexible start and end times.
A dedicated host is a physical easy to server
dedicated for our use
we might use. This isn't type for compliance
or application licensing reasons such as VM wear
or Windows Server.
These can be purchased
and it could be purchased as a reservation for up to 70% off of the on demand price.
So there was lots of new information in this video,
and I certainly don't expect you to memorize it all.
In the upcoming lessons. We will launch our own easy two instances and even write a script to load them automatically.
Then these concepts will begin to make much more sense
and begin to click
What is Amazon easy to,
and what does it do for us?
Elastic compute clout
provides us with scalable computing capacity
in the Amazon. Web service is cloud
and easy, to instance, helps to eliminate the requirement for us to spend money on hardware up front.
What is an Amazon machine image?
An Amazon machine image or am I tze are pre configured templates. For our instances,
the A M I will pre package the basic image that we will need for our server, including the operating system and additional software.
What are the four ways to pay for Amazon? Easy Two instances
The four ways to pay for
easy two instances are
and dedicated hosts
in this video,
we provided an overview of Amazon. Easy to
we introduced Amazon machine images or am I CZ.
We explored the different instance types,
and we explored the concept
of elastic block storage.
