AWS VPC | Create New VPC with Subnets, Route Tables, Security Groups, NACL | AWS Beginners Tutorial

[Music] hello friends welcome back to LAN antegrade tutorials some of our followers have asked to make a video on a double V PC with step by step procedure of how to create a new virtual private cloud in EA Tobias based on the requirement provided by the company from scratch along with subnets router tables Internet gateway and how to associate all these components so here is a video before creating any infrastructure in Erebus cloud we should have some plan about the infrastructure and architecture designs like how many IPS we want for our resources how many subnets to be created and in which availability region and zones should be used this V PC so we should have answer for all these questions to make you understand better let's use this sample V PC architecture as Mayra comment and I will show you how to build the same infrastructure design in area bridge clout so this is a sample architecture diagram of a database V PC that is Amazon Web service virtual private cloud so what is virtual private cloud it is a virtual network that can be created in public cloud when you have Erebus account with sufficient access it is logically isolated from other virtual networks in the area bridge cloud based on our requirement it can be created you can specify an IP address range for the V PC you can add subnets you can associate security groups and you can configure the router tables so that we can launch our database resources like Amazon ec2 instances within this V PC so this architecture require one be pc with 10.0.0.0 / 16 IP range within that we need to create two subnet one is public subnet and other one is private subnet with endur'd 0.14 public and tender 0.2 for private resources which will be created within public subnet we have a IP range of 10.0 at 1 and within private subnet resources will have a range of IP that is 10.0 dot 2 then this public subnet is attached to Internet gateway so any resources created within this public subnet will have internet access that is why we call this subnet as public subnet why because it is connected to the Internet gateway but any resources we think private subnet will not have access to external world so this is the actual difference of public and private subnet then how can we protect our AWC resource from Internet world here Breece has multiple layers of security to avoid these kind of attacks and also to control the traffic's like security groups and network access control list I will explain you all these things while creating the network architecture select a document of this video and other links are mentioned in the description below refer those links to understand this session much better from basics if you still dream subscribe to our channel do subscribe now and click nearby Bell icon to get the updates immediately let's get started in order to create and manage any a debrief services we must have some valid users created with I aim policies yes you will not have access to these era breezy resources once you have the access log into the aerialist management console this is a sign page where you have to enter your email address along with password and you'll be asked to enter the MFA code that is on your mobile you have to register that Google Authenticator through which you can get that code and this is the main dashboard of a breeze management console you can select any region as per your requirement but I am logged into u.s. East North Virginia region once you are confirmed with your region go to service and and type V PC in this search box it will give you the list of services which is matching with this pattern so here you click this V PC this will take you to the V PC dashboard so this is the V PC - put where you could see all these summary of your VP see here I have no VPC no subnet nothing is created because I have deleted my default VPC here go to your V PC click create V PC here is a page where you have to give all your teachers about your V PC give some name for this V PC like this you can create n number of V PC within your area B's account for example if you wanted to create a dedicated V PC for eBay for example then you can just give a name something like eBay b pc like that so I just give my demo v pc IP range as per the diagram it must be 10.0.0.0 / 16 reach and let it be the default one we don't want I P v6 and tenancy let it be the default so just click create so you will get the confirmation message like the following V PC was created and this is your V PC ID thus closes message once you have created new V PC you will see all the V pcs available in this region including the newly created one my demo V PC and it's V PC ID and the IP range and all these details once this is done let's create Internet gateway so Internet gateway it enables your instances to connect to the internet through the Amazon network so without this internal gateway you not be able to connect to the external world so click create Internet gateway here you have to give just the name and just click create here if you see the state it is detached so we need to attach these internal gateway to our V PC so just right Li and attach to V PC or you just select this and go to actions here also you have the same options so attached to V PC here it will ask you to which V PC you have to attach these internal gateway if you are having multiple V pcs obviously you have to select the vpz right so here just pull down and here you will have the V PC ID as well as the name water given while creating the VPC so just get my demo VPC that's it attach these attached to our VP Singh let's create subnets so we need two subnets one is public subnet and private subnet so a subnet is nothing but it is a range of IP address in your PC so you can launch a WC resources into a specified subnet use a public submit for resources that must be connected to the Internet and use a private subnet for the resources that won't be connected to the Internet Kota subnets we have no subnet sofa create subnet name let me give public subnet so that it will be easy for us to identify what subnet it is so named again you have to select the V PC availability zone is nothing but you have a different different zone in each region if you have any preference just click here you can select any one of this if you have no preference then just let it be arab list itself it will select any one of it so ipv4 for public subnet this is our range create it is created closest now create private subnet select the V PC here the range should be 10 dot 0 dot 2.0 24 create so we have created two subnets and these two are attached to these V PC and this is the range of it let's create route tables by default when you have created a V PC automatically one route table and one network access control list will be get created so you can use this route table itself as any one of your route table let's say public throw table these already created so just rename this name so that will be easy to understand either you click Edit here itself you can give private RT and click click mark yells lightly add our ad tags or action add or edit tags anything should be fine so I just click Edit tags here create tag key name and what is the name public RT which means the public row table let's create private row table click create row table select the V PC click create closest box we have public row table and private route table now select the public road table this is where you have to add all your public subnet and your internet gateway so that this will become the public network here click routes these are the entries it has just click Edit routes click add route from any AP and targets select the Internet gateway what I have created there is my demo internal gateway and click Save routes successfully edited this closes so here in this public route we have one more entry that is Internet gateways attached so this become a public network now again we need to attach the public subnet to this public route so go to subnet Association here edit subnet associations here you will see all the subnets are available here just select the public one don't select the private just select the public one because this is a public crowd table and click Save now go to private crowd table here you don't need to add any routes let's go to subnet associations to associate your private subnet to this private route table hit submit select the private one and click Save and also we need to create security groups and nacl so that we can protect our header bridge resources from Internet so this is the security where you have network ACLs and security groups Network ACL is a security layer within the network level and the security groups is a security at the instance level so you have to attach any of these security groups to the instances so first you create a security group already it is created the default one so what you have to do is just rename it here you have inbound rules and outbound rules so this is where you have to edit the rules inbound which means the traffic which is coming to instances from outside network and this is the outbound routes from easy to the traffic which is going to outside the network so edit rules so inbound rules control the incoming traffic that is allowed to reach the instances add one more rule select all traffic and here in the custom you can give my IP so that only from your IP will be able to access these instances if your instance is having port number 22 or 80 or 443 anything all ports we can access all these instances because we have selected all traffic's if you want to restrict that too then you have to select the particular port for example if you want to take one Lee SSH connection to that instances then you can use only SSH so I give all traffic for now so that I will not have any problem to access my instances and make sure you have selected my AP if you give anywhere around the world anybody can access your instances so this is not recommended so please not use this anywhere in any of these rules so my IP this is my IP so just copy this we can use this IP in NaCl here you can give some description about this particular IP what it is save rules now go to NaCl here also it is created by default so just rename this click inbound rules by default they are allowing all traffic from anywhere this is not safe so edit inbound rules just remove this and replace with your IP for now so nobody can access you are easy to why are this VPC so we have edited our nacl rules do not allow anybody except this IP if you want to add more IPS then you can just click add rules click Save now so based on this diagram we have created our V PC enables account let's create - easy - one is within this public servant and other one is within private subnet let's see which one I am able to access it obviously I will be able to access the easy to which is created within public subnet because Internet gateways attached but I will not be able to access these easy to but you go to service ec2 click instances launch instances I'll go with free tire 1d let it be these Amazon am ice number of instances one for now because I'm going to attach these instances to particular subnet that is public subnet auto assign public IP yes by default disabled so make it enable and this instances will be created under this V PC if you have many V PC it will show you the list you select the particular V PC the resolve okay just next at tax ok security group this is where you have to select your security group to associate with these instances here don't create the new security group if you want to create then you can create it but already we have edited the rules so select the existing one yes select the correct security group and here it is listing the list of rules we have allowed only from this IP for all traffic so I'd be able to do pink I would be able to connect to these instances everything I can do it so review and launch let me create a new one download keep this file in a safe place because once it is deleted you cannot be recovered so better you add it in a version control or something launch instances instance is creating meantime I am just giving the name it is created and running straight so if you see it has got IP public IP that is 126 to 0-7 2 3 9 and we have attached these easy to with public subnet let's create one more we'll add this instances to private subnet Ottawa's in public IP enabled anyway this in private subnet doesn't matter even if you have public IP nobody can access that from external world rest all okay just review and launch before that we need to add security group select the existing one so only difference I have done here is one easy to I have used on public subnet and the other one have used in private sub not even to this easy to I have given complete access from my IP let's see what happens review and launch choose an existing one I'm going to use the my demo key simply this is a private easy to there's also got public IP and public got this IP if you see the VP see local IP the public got in this range this is what we have defined in the one series right and for the private - series so both are running now copy these public IP and try to pink I'm getting the replay from that easy to now go to private and copy these public IP so you'll not be able to access that easy to even the security group is allowed for your IP the reason behind is this ec2 is lying on private subnet where the internet gateway is not attached so that's it so exactly similar to this diagram we have created our V PC and subnet inner gateway and router tables hope you got an idea keep practicing and have fun how did he feel is it helpful appreciate our
