AWS In 10 Minutes

AWS In 10 Minutes


hello everyone today we’re going to talk about AWS in 10 minutes let’s look at the agenda

here let’s talk about what AWS is why it’s such a big hit we’ll have a look at the overview

of the services, we’ll see how much it costs how big it is and what the future of AWS is so

what is AWS everyone is talking about Amazon Web Services but let’s have a look at what it is it’s

basically, a global cloud platform which allows you to host and manages services

on the Internet, it’s used by almost 80% of Fortune 500 companies to host their infrastructure

and it has a lot of services which it provides to its customers there’s infrastructure service which

means they provide fair servers as a service so you don’t need to manage the backup and the power

supply of the service they provide a platform of the service you can get Java Ruby PHP as a service so

that you don’t have to manage the binaries of these applications you get software as a service where

and you get email sending capabilities like SES you get queuing services like sqs and it’s a cloud storage

platform where and you have a lot of storage options including EBS and s3 so all in all AWS is a

hosting provider which gives you a lot of services wherein you can run your applications on c

now let’s take a look at why it’s such a big hit so everyone is trying to use AWS everyone is

trying to put their applications on the cloud so what’s the reason that AWS is the top provider

and the top choice for doing anything on the cloud one of the biggest reasons is the billing so the billing

is very clear you get a per hour billing every instance or every service has a micro-billing

so be it instances on ec2 you get per hour billing rate which is very transparent even s3 buckets

are charged on a per GB basis although it is a storage service, but still there is micro-billing available

there the signup process is easy you don’t need to sign any agreement nothing you just go sign up

with an email id add a credit card and you’re good to go you can go from zero to 100 in just two minutes

you can launch your servers big machines without buying hardware without procuring

any hardware you can just be up and running in minutes so they’re billing dashboard is also very s

simple they give you an integrated billing dashboard which gives you reports you can pull out

reports every month you can pull out reports based on services based on

various parameters for the cloud provider to be a hit you need it to be stable it has to be a trusted thing

so their services are quite stable in the last seven or eight years they have seen some three or four major

outages but those have been only region specific so that means out of the 12 or 13 regions in which they operate

the outages have been region specific in a particular country or continent and those also have not been

more than two or three hours and have not affected all of their customers it’s a trusted vendor so

when we talk about AWS

it comes up with something which is used by everyone in the industry from s

mall startups to big enterprises everyone sees Amazon as a trusted adviser now let’s have an overview

of the most commonly used services so the first and the most commonly used service is EC 2 which

is Elastic Compute cloud this is the service which gives you bare servers so this service will

give you a machine which you can launch and you can run your software on those you can get small

or big machines based on your requirements the second choice is VPC so Amazon will not allow you

full control of their cloud instead they give you chunks of their cloud which is VPC or the virtual private cloud

so VPC lets you create networks in the cloud and then run your servers in those networks the next one is s3

which is simple storage service so s3 gives you the opportunity to upload and share files so does mostly

a file storage and sharing service then you’ve got RDS which is relational database service so this RDS

allows you to run and manage databases on the cloud so they’ve got almost all the major flavors of databases

right from SQL Server to Oracle and MySQL PostgreSQL they have recently launched another one which

is called aurora which claims to be a very high-performance database then route 53 is therefore DNS

so they’ve got a managed DNS service where and you can point your DNS to Amazon and they take

care of the stuff so it’s a global DNS service it’s a scalable DNS service so it scales according to demand

here’s also elastic load balancer the ELB is a service which gives you the opportunity to load balanced incoming

traffic to multiple machines so this way you can scale up your web applications to any number of users you’ve got

autoscaling which adds capacity on-the-fly to elastic load balancers so that your website or your

application is never down due to a load how much does it cost this per hour billing is already mentioned for

everything if it’s something like a storage thing again there’s a per hour or per GB month storage so

I think there is region specific pricing so Virginia is the cheapest region out of all of them so the region

specific pricing is because they have got some regions which they have got a good hold of and they are the headquarters

so Oregon and Virginia are the cheapest actually they also give you services based on the term so

if you sign up for something for a year it would be cheaper for you rather than signing up for

something on an on-demand basis so they’ve got reserved instances which are

very cheap as compared to the on-demand ones you can get discounts from 20% to almost 60% if you sign up

for a three-year term, they are spot resources examples of these are spot instances so this is like a bidding market

a base where you can bid for a price the only downside of this kind of pricing is that your machine might be terminated

or your resources might be terminated if someone bids higher people use these kinds of things for doing some ad

hoc in search or some ad hoc tasks which are really not critical how big is it they have got 15 regions

across two major countries of the world, they’ve got regions in the US Europe Asia Pacific they’ve got a global

footprint so in today’s world if you are anywhere in the world you would have a region within 1,000 miles of your location

they’ve got massive data centers so each of the regions has got multiple availability zones so one availability

a zone can be thought of as a big data center the data centers have anywhere from 300,000 to 500,000 servers

what is the future of AWS so they currently have 64 services which span across infrastructural service software

as a service platform as a service they are launching new services in all demands every day right now they

couple of services which focus exclusively on machine learning and they are focusing

on software as a service product wherein they want to take control of the service you want to utilize

they don’t want you to do it they want you to upload it to them and every now and then they keep on reducing the

costs so you would hear it in the blog that okay the price of ec2 machines has been reduced and this is because

of their scale so they scale up and they give the cost-benefit to the customer that’s all for today guys

with just a quick intro of the Amazon Web Services cloud
