Everyone when developing your websites has to decide their hosting plan at some point. While AWS VPS hosting might be a familiar name in the cloud industry, many are still unclear on what it is all about.
That's probably why you are reading this. There is no need to worry anymore as you'll be getting exposed to all you need to know about AWS VPS hosting in this article.
What is the difference between AWS (VPC), VPS and Shared Hosting?
The difference between AWS (VPC), a VPS and Shared Hosting leaves many confused.
Let's take a look at what each stands for, how they differ from one another and which one is best for you.
Shared hosting is when many websites are connected to one server. What happens in shared hosting is that a server machine running a software set that can run a website is provided to multiple users. This software includes a web server like Window IIS, Apache, Tomcat etc., a server-side language like Java and Php and a software database management software like MySQL, PostgreSQL etc.
In shared Hosting, the site shares a physical server with other websites and the server resources are shared equally among the websites on the server.
Sometimes shared hosting can host up to 100 websites, it all boils down to the capacity of the server
Features of Shared Hosting
The economic friendliness is the reason many choose shared hosting. Shared Hosting is the best for businesses in their early stage. At that point, when there isn't much traffic on the website. However, you might have to move to another hosting plan when you start experiencing an increase in traffic.
Another advantage of shared hosting is that all a server needs to work is taken care of by the providing company.
Shared hosting services generally provide CPanel. CPanel makes the handling of website hosting easy for a beginner. Additionally, CPanel provides GUI for file handling. This makes file handling possible without the knowledge of FTP and SSH.
Shared hosting is the best option for anyone who is just learning website development and does not want to face the hurdles of setting up a server by themselves.
As good as shared hosting, it is not without flaws.
In shared hosting, you do not have the root access to the server, meaning installation of extra software or service on the server machine is impossible.
Also, your website will start showing errors when the website gets high traffic due to resource overload.
Sometimes you might even experience server crashes, or your hosting provider may decide to take down your site temporarily to prevent other sites from being impacted.
Virtual Private Server(VPS)
A VPS is an independent server dedicated to you.
In setting up a VPS, you can decide to opt for custom setup, doing the installation by yourself.
Alternatively, you can opt for a server set up. Most Hosting providers have a one-click standard installation for pillar configurations such as Ngnix with Python, Python with MySQL and Apache or configurations like LAMP- Linear, Apache, MySQL and Php.
Features of VPS
In terms of cost, VPS Hosting plans are moderately cheap, especially when you put into consideration that it is a dedicated server.
Most VPS hosting plans do not come with the option of stopping the server once the plan is initiated except the subscription is over, and your server will be shut down if that happens.
Since the resources are dedicated to you alone and not shared, your website will be fast and responsive. However, you will be the one to cater to all the security needs of your website.
Unlike shared hosting, you have root access to the server. Additionally, you can even become a hosting provider and have multiple websites on your server. Just set up a WHM panel and that's all.
VPS hosting also has its disadvantages.
An example is the free CPanel available in shared hosting. In VPS hosting you have to pay an extra fee as CPanel is considered a paid service.
If your traffic increases and puts pressure on your server resource, there is no way to provide additional resources at run time.
Virtual Private Cloud (VPC)
In VPC you, all resources are available on-demand because they are in the cloud. Just likeVPS has a virtual machine, a VPC has a virtual machine too. The difference between the two is that a VPC machine has infinite resources, while a VPS machine has a fixed configuration.
Features of VPC
In contrast to VPS, VPC resources are in a single physical location.
In a VPC you can switch on and switch off the server at any time. This will help in cutting costs when you are not using the server.
VPC provides elastic cloud services, so it is easy to expand your website.
A VPC service can also give you up to 100% uptime.
If your website's traffic increases,VPC service provides additional resources that match the traffic increase without affecting the server.
How to run VPS in AWS EC2
Setting up a VPS in AWS EC2 can be a difficult task for someone who doesn't have the experience. You do not have to worry yourself about the setup, here are 11 Simplified steps to run a VPS in AWS EC2
1. Set up an AWS account.
To do this type aws.amazon.com in your browser and follow the prompts to set-up your account.
2. Set up a free instance: After setting up your account, the next thing is to set up a free instance.
- Login to your AWS console page.
- Choose a datacenter location- this is where your instance will be created.
3. Use the EC2 and choose your image
- On the Member’s Dashboard, select AWS and click EC2 to access the service.
- Click the launch option to see the instances types available.
- You can also upload your image
4. Select Amazon Machine Image:
- Click the OS system you want and select the free tier only option. This will let you see the available images for the micro instance option you choose.
Note: There is a wide range of Operating Systems available on Amazon AWS so ensure you choose the right option.
5. Choose instance type.
- Click the default instance option and input t2.micro.
- Tap the "Next: Configure instance details" button on the bottom right corner of the screen.
- Click the Review and Launch button. Select Add storage and edit your storage location.
- Move on to the tag instance and create your choice of Tags.
- Go to configure security groups. Here you can give a name to the security group and description.
- Add Rule SSH, HTTP, and HTTPS so that the VPS can function as a web server.
6. Launch the instance
- Go to the page settings and click the “Launch” button. A security warning will pop up, ignore it.
You will be asked to check your page settings for errors, and if there is one, you can make corrections on that particular page.
7. Select a key repair
Before you complete a VPS launching process on AWS, you'd see a dialogue box. This would require you to choose a key pair you'll be using for the instance.
A pair of keys is made up of a private and public key. The private key is stored by the user and the public key by AWS.
Selecting a pair of keys helps in identifying the real user of SSH to connect to the instance once when it is running. To choose a key pair
- Click the create a new key pair button on the name and type the name for your key pair.
- Download the and save the file in a safe location. It would be best if you store the pair of keys in a file you can easily access as you will need it in future.
- After doing all these, tap the Launch instances button
8. Set up secure permissions for the key file
Except there are secure file permissions SSH will not allow access to the pair of keys file created.
To set up file permission:
- Go to file manager Right-click the file and select Properties from the menu. A window will come up, click the permission tab.
- Set the access permissions as Read-only, the group section as none and other access as none and tap the “Close” button.
9. Manage the instances
After launching the instances, the next to do is to start managing them.
- Click the view instance button
- On the AWS tab, you would see the instances created.
- Once you click the tab, you would see two instances, an instance created before and the next example in the initial stage
- Wait till the instance status changes to running before logging in.
10. Log in to the VPS
Logging in into a running instance is now made easy by the use of SSH Protocol. While macOS and Linux come with an inbuilt SSH, you have to install a Free Putty program to access the instance on Windows.
Also, you have to know your Instance IP address before you can access the VPS. To know your IP address, click the checkbox beside the instance.
Note: once you restart an instance, it will get a different IP address.
11. Using SSH Service
If you want to use the SSH services, use the pair of keys file generated to login to the instance.
If you want to stop the instance, click the running instance and tap the Actions button. From the menu, select Instance State and click stop. You would get a confirmation message.
All these are steps involved in setting up and managing a VPS on EC2
Managed Services for AWS
Amazon has a feature called AWS Managed Services(AMS), which helps its customers manage their AWS resources.
AMS helps customers operate AWS on their behalf. This service is beneficial for startups who are moving towards adopting the cloud at scale. It is also helpful for newbies who need time and support to gain skills and experience in AWS.
AWS Managed Services help its customers reduce risk and operational overhead by adhering to the best practices for infrastructure maintenance.
Benefits of AMS
There are several benefits of AMS, let's take a look at Five Benefits of AMS
- Incident Management
AMS helps you to monitor your infrastructure resources health. Not only does it monitor, but it also handles investigating and resolving incidents daily.
For instance, if an EC2 experiences instance failure, AMS will detect the failure and launch another instance. It will also take the necessary action that will minimise or totally eliminate service interruption.
AMS service deploys, validates and personalises all its components, giving support to customers that need total help solely out of one region and supporting the redundancy plan requirements of their region.
With AWS Managed services, you get commitments for the essential aspects of service.This ensures that for your AWS infrastructure, you get a high level of operational services.
- 24/7 Support
AWS Managed Services uses its wealth of cloud engineering expertise to answer questions, perform and manage complex change request and resolve incidents.
They provide all the support to accelerate your cloud operations.
- Security and Access Management
AWS Managed services used intrusion protection and detection, and anti-malware protection systems to manage security policies. AMS also recognise and respond to any form of intrusion as swift as possible.
AMS takes out the difficulty of managing multiple mechanisms for authentication by configuring default AWS security best practices. This lets you access AWS resources by using your corporate credentials.
- Patch and Continuity Management
AMS applies critical security patches immediately and applies others based on the schedule you request.
AMS uses Amazon EBS and TDS snapshots to automate backing up of stacks. So if any outage or failure happens, they can be restored easily.
