Q & A
What does EC2 stand for?
-EC2 stands for Elastic Compute Cloud, which is a service offered by Amazon Web Services (AWS).
What is the primary function of EC2?
-EC2 allows users to rent virtual machines, store data on virtual drives, distribute load across machines, and scale services using various AWS tools.
What are the components of EC2?
-EC2 includes EC2 instances (virtual machines), EBS volumes (virtual drives), Elastic Load Balancers, Auto Scaling Groups, and Security Groups.
What is the significance of being able to choose the operating system for EC2 instances?
-Users can select between Linux and Windows operating systems for their EC2 instances, allowing flexibility based on their application requirements.
Why is it important to choose the right instance type for EC2?
-The instance type determines the compute power, memory, storage, and network performance, which are crucial for the application's performance and cost efficiency.
What is the difference between EBS and EC2 instance store for storage?
-EBS (Elastic Block Store) is a network-attached storage, while EC2 instance store is hardware-attached storage. EBS provides durability and persistence, whereas instance store is faster but ephemeral.
What is the role of the Elastic Load Balancer in EC2?
-The Elastic Load Balancer helps distribute incoming application traffic across multiple EC2 instances, improving fault tolerance and availability.
What is the purpose of Auto Scaling Groups in EC2?
-Auto Scaling Groups automatically adjust the number of EC2 instances in response to demand, ensuring optimal resource utilization and cost efficiency.
What is the AWS Free Tier for EC2 instances?
-The AWS Free Tier includes up to 750 hours per month of t2.micro instances, allowing users to run these instances continuously for a month without additional charges.
What is the significance of the EC2 user data or bootstrap script?
-EC2 user data is a script that runs at the first launch of an instance, allowing users to configure the instance automatically, such as installing software or setting up environment variables.
Outlines
🚀 Introduction to Amazon EC2
This paragraph introduces Amazon EC2, which stands for Elastic Compute Cloud and is a fundamental AWS service for infrastructure as a service (IaaS). It explains that EC2 is not a single service but a collection of services that allow users to rent virtual machines (EC2 instances), store data on EBS volumes, distribute load with an elastic load balancer, and scale services using auto scaling groups. The paragraph also touches on the flexibility of choosing the operating system (Linux or Windows), compute power, RAM, storage options, network type, and firewall rules (security groups) for EC2 instances. It concludes with a mention of the EC2 user data for bootstrapping configurations upon the first launch.

EC2 allows you to rent virtual machines, known as EC2 instances, with various configurations.
You can choose the operating system for EC2 instances, either Linux or Windows, with no option for Mac.
EC2 instances offer a range of options including CPU power, RAM, and storage space.
Storage options for EC2 include network-attached EBS or EFS, or hardware-attached instance store.
EC2 instances can be configured with different types of network cards and public IPs.
Security groups are used to handle firewall rules for EC2 instances.
EC2 user data allows for bootstrap scripts to configure instances at first launch.
EC2 instances can be customized extensively to fit the needs of various applications.
Different EC2 instance types, such as T2 Micro, T2 X-Large, C5 4xlarge, and M5 8xlarge, offer varying capabilities.
T2 Micro instances are part of the AWS Free Tier, providing up to 750 hours per month.
The power of the cloud with EC2 is the ability to rent compute resources on-demand.
EC2 instances can be scaled using Auto Scaling Groups or Spot Instances for flexible resource management.

Understanding EC2 is crucial for grasping the concept of cloud computing and its on-demand nature.
The course will delve deeper into EC2's practical applications and additional options for users.
The flexibility of EC2 instances enables users to choose the exact specifications they need for their virtual machines.
Transcripts
on ec2 in which we will create our first
website on AWS so what is Amazon ec2
well ec2 is one of the most popular of
AWS offering it is definitely used
everywhere and what is it
well it stands for Elastic Compute cloud
and this is the way to do infrastructure
as a service on AWS
so ec2 is not just one service it's
composed of many things at a high level
so you can rent virtual machines on ec2
they're called ec2 instances you can
store data on virtual drives or EBS
volumes
you can distribute load across machines
elastic load balancer you can scale
services using an auto scaling group or
a SG and all these things do not worry
we will see in depth during this course
knowing how to use ec2 in AWS is
fundamental to understand how the cloud
works because as I said from before the
cloud is to be able to rent the compute
whenever you need on-demand and easy to
is just adds so ec2 what can we choose
for our instances so the our virtual
servers that we rent from AWS well we
can choose the operating system could it
be Linux or Windows and as you notice
there is not Mac so you cannot rent a
Mac from AWS you can just rent a Linux
or Windows
how much compute power and cores you
want on this virtual machine so how much
CPU then you need to choose how much
random access memory or Ram you want and
how much storage space so for example do
you want store it is going to be
attached through the network and we'll
see that it's with EBS or EFS or do you
want it to be Hardware attached in this
case it will be an ec2 instance store
and with the whole section on storage so
don't worry about it and then finally
the type of network you won't attach to
your ec2 instance so you want a network
card is going to be fast what kind of
public IP do you want and finally we
need to handle the firewall rules of our
c2 instance and that is the security
group and I lied finally finally there's
the bootstrap script to configure the
instance at first launch what's called
the ec2 user data so we have lots and
lots of options and as you'll see in the
hands-on
even more options at other certification
levels that you need to know in ec2
instances but at a core of it what you
need to remember is that you can choose
pretty much how you want your virtual
machine to be and you can rent it from
AWS and that is the power of the cloud
you can do this by just in the blink of
an eye really so what type of instances
do we get for ec2 and this is an example
I have hundreds and hundreds of ec2
instance types but here are five for you
so the first one is a teaching micro
very very simple it has one V CPU 1 mm 1
gigabyte of memory the storage is only
for EBS and has a low to moderate
network performance but as soon as you
increase the instant type right in the
pool if we stay in the same family so we
stay in the t2 family we go to t2
x-large now we have access to 4 dcpu-16
megabytes of RAM gigabytes of RAM sorry
and network performance of moderate if
we go to completely different new levels
so c5 g4x large which is a very
complicated name you get 16 V CPU so 16
cores you get 32 gigabytes of memory so
a lot more you get some storage that is
attached to your ec2 instance this is
why it says 400 and VME SSD now the
network is going to get really good up
to 10 gigabytes as well as the bandwidth
to talk to network storage and so as you
can see if you go to our 560 next larger
m58 x large again you have different
characteristics so the idea with this is
that you choose the kind of instance
that fits best your application and you
can use that on the cloud on demand ok
now for this instance for our course t2
micro is going to be part of the AWS
free tier you can get up to 750 hours
per month of t2 micro which represents
basically running that instance
continuously for a month and so this is
what we'll be using in the hands-on that
comes in the next lecture so this is was
a short introduction to EC - don't worry
is gonna get very very practical very
soon I will see you in the next lecture
