The Importance of a VPS for a WordPress Site

Many younger businesses just starting out do not have Virtual Private Servers. But as they are becoming more crucial to how businesses manage their data, a VPS is a low-cost and effective approach. A Virtual Private Server is akin to a physical server that allows you to allocate resources for any job in a streamlined fashion. For the uninitiated, VPS falls under two distinct banners: Unmanaged VPS and Managed VPS. An Unmanaged VPS is the responsibility of the software owner. Amazon Lightsail is a Managed VPS. Therefore, it is not the client's worry to maintain it, for example, configuring, upgrading, or installing software.

About AWS Lightsail

Amazon Lightsail which can be used to host a WordPress website is a VPS service on the AWS cloud platform. With memory going from 512 MB up to 8 GB, data transfer allowance between 1 and 5 TB, and processes going between 1 and 2 cores, it is a comprehensive package, especially for those starting businesses looking to make their way protecting their data more comprehensively. It also includes a Virtual Machine (VM), which includes SSD storage, DNS (Domain Name System) management, data transfer options, and a static IP. It also includes the following features:

• Simple and straightforward load balancing to make processes more efficient.
• A powerful application programming interface (API) improves your ability to develop applications. It also allows you to integrate with external applications.
• The console allows Secure Shell (SSH) access.
• Additional access to other AWS services, such as CDNs (Content Delivery Networks) and managed databases.
• Secure networking capabilities so you can configure the details to gain access through your IP address, DNS, and the firewall.

Why Should We Choose Amazon LightSail?

There are a wide variety of reasons to use Amazon Lightsail. It is an ideal beginner software for first-time cloud users and developers. Its benefits are as below:

• A cheap subscription makes it affordable for most beginner businesses. It is free for the first month, and its cheapest cost is only $5 per month. Depending on the memory processor, SSD disk, and transfer options you need, it can go upwards, making it an ideal option for those who need to scale their business.
• A wide variety of benefits from the AWS ecosystem, including technical and non-technical training, request marketing, and additional business support (as well as the opportunity to connect with other APM partners around the globe).
• Simple to use interface. The UI runs through pre-installed software resulting in less confusion for those using it for the first time.
• Familiarity with the Amazon brand. Companies or developers using AWS for developing applications or web hosting benefit from the tried-and-tested brand name, making it a more enticing prospect.
• A very reliable system. Services are run through the Amazon infrastructure, which means the likelihood of replacement is slim.

Do I Need to Buy Amazon LightSail When I Have Amazon EC2?

Amazon Lightsail is a suitable option for the first time cloud user. Developers looking to test out any app prototypes or young businesses that need a limited dose of data protection will yield its benefits. However, the Elastic Compute Cloud (EC2) has long been the go-to option. If you have Amazon EC2, it's unlikely the Lightsail will meet your needs.

Amazon Lightsail is geared towards businesses and developers looking to start in cloud computing. Amazon Lightsail is used for simple web applications, whereas EC2 makes its mark on big enterprise web applications. Amazon EC2 works with numerous VMs. The larger-scale companies that have needed an infrastructure to use big data and analytics will find that Amazon Lightsail doesn't give them what they need.

However, Amazon Lightsail is fantastic for WordPress websites that use facilities such as WooCommerce and customized websites. Because Amazon Lightsail has one single VPS, when you compare this to the scale of Amazon EC2, this can leave the experienced business owner or developer disappointed. But for companies starting and app developers that need to prototype and layout a test environment, Amazon Lightsail is a fantastic, low-cost option. Therefore, it is ideal.

Conclusion

Overall, we like this product. It will not break new ground for established businesses, but for the first-time cloud users and developers out there, this is a perfect starting point. Startups and companies operating on a small scale will make the most of what Lightsail delivers. Due to its useability, easy interface, and scalability, the Amazon Lightsail software is an ideal stepping stone into cloud computing. Companies looking for a reliable provider may find themselves thinking twice about certain cloud providers. Still, due to Amazon's familiarity and scale, it is the perfect place to begin. As it has a simple UI, Amazon Lightsail can easily integrate your business into numerous benefits you may not have had before. Also, the AWS ecosystem provides great support, and its affordability, combined with the fact that it is easily scalable, makes it a great choice.

Companies, app developers, and small-scale production companies will benefit from its wide variety of resources. Still, those already au fait in the ways of Amazon EC2 will not need to acquaint themselves with this software. However, as a foundation for cloud computing, it provides the perfect entryway for anybody that has never learned how to look after their data. Also, those that thought cloud computing was a limited package that didn't have a wide variety of features may find themselves pleasantly surprised. Overall, we give it an impressive 4.5 stars.

A Few Essential IT Concepts

Let’s delve a little into a few critical IT definitions to understand what we’ll be doing.

• High Availability. In the world of information technology, high availability relates to a system that can operate well, on a previously agreed level of operational performance, for a long time. To fulfill the standards above, the system must be free of interruptions and disruptions for a higher-than-average time. High availability also relates to systems with redundant components, an infrastructure that AWS makes much more comfortable.
• Scalability. It pertains to a system’s ability to automatically increase or decrease its sources depending on the level of user demand. Several AWS Resources provide scalability, namely ELB, RDS, S3, and EC2.
• Distributed Services / Loose Coupling. An approach in which different components within a system are interconnected to the point of loosely depending on each other to function correctly. We perform loose coupling to have dedicated hosts for a single service, and also to leverage loads.

This is what the ideal, highly scalable WordPress architecture should look like:

Amazon Web Services

What exactly are the Amazon Web Services, and what do they do?

Virtual Private Cloud

VPC allows enterprise customers to have a private network to place their cloud computing sources. Nobody outside the enterprise in question has access to this cloud.

Public Subnet

Not unlike a website’s server, a public subnet is a subnet to place the resources we’re interested in making public. It’s associated with a route table, which in turn leads to an Internet gateway, thus connecting the VPC to the broader web.

Private Subnet

Contrary to the public subnet, the private one is the place to deploy all the resources we want to be hidden from outsiders. For our current architecture, we’ll place the database on this application.

CloudFront

This content delivery network is dedicated to sending content faster to end-users. This is done through a global network of proxy servers that cache heavier content, such as videos and other media. By using CloudFront, users will receive the multimedia content on WordPress through the closest edge location available, in turn making the experience quicker.

S3 Or Simple Storage Service

S3 works alongside CloudFront to make the end product faster for users. This storage solution is where WordPress will get its content whenever it scales, whether it’s up or down. It’s the very scalable structure that Amazon uses on its global network.

EC2 or Elastic Compute Cloud

This AWS is focused on acquiring extra computing power by allowing companies and other users to rent “virtual computers” to run their respective applications.

RDS & Multi A-Z

An entirely free service managed by AWS, it enhances the durability and availability of Database Instances. In all, this is where we’ll host the WordPress Database. Enabling the Multi-Availability Zone feature helps a lot with availability. Plus, this service has an excellent feature for scalability: RDS instances can replicate among themselves.

Route53

One of the most basic services on the AWS arsenal, it’s a Domain Name System (DNS) of a very scalable and available nature. It allows users and companies to manage traffic and upcoming all-around requests.

Load Balancer

Also called Elastic Load Balancing, this application distributes traffic load among the different available instances. It allows handling the scalable load across different availability zones or directly handling traffic within a single availability zone.

Autoscaling

This application will be the very foundation of our scalable and highly available WordPress site. Auto-scaling automatically adjusts the site’s capacity to become more efficient, namely steady performance at a low cost. Thanks to this, the outside public will receive the least possible amount of instances, and whenever something goes wrong, auto-scaling will replace it with a healthy instance.

Cloudwatch

Cloudwatch is the AWS monitoring service, and it’ll track predefined or default metrics, including networking, and memory usage.

EFS or Elastic File System

Running on the AWS public cloud, it’s a cloud storage service dedicated to applications and workloads within the system. It replicates content faster, yes, but we might not use it that much when solely sharing WordPress files.

How AWS Work Towards Creating a Highly Available Site

Once everything is set in place, this is what your traffic flow will look:

When setting up the services above, your site will be able to serve millions of visitors, all of whom will get the same quality. Whether you’re experiencing a surge in traffic or a particularly low moment, the site will be able to meet your needs. Here’s how it will look when your traffic increases:

Meanwhile, your AWS resources will look like this:

The Actual Site Architecture

Now that you’re familiar with the AWS functions above, here’s what you should be crafting for the optimal site architecture:

• CDN or Content Delivery Network. Makes your content faster by spreading it around the world and hosting it on a network of servers.
• Memory Performance & CPU. We’ll be able to scale, either up or down, depending on the memory metrics and CPU. Traffic won’t cause overload due to lack of memory, leading to 500 errors, because the response time will remain the same between the different servers.
• WordPress Server Caching. Also known as server side-caching. Whenever a website visitor requests a page, that request goes to the database to search the page’s information. Caching creates a temporary file instead of taking the extra time to process on the database, in turn making things faster.
• Instance Types. Choose the right AWS instance type for the workload your site manages. You’ll also need to select the appropriate number for resources for it to work smoothly.

Extra Notes

Now you’ve built the proper architecture for a scalable WordPress site on Amazon Web Services! Here are a few good practices:

• Don’t get caught by surprise, and configure Cloudwatch to notify you if anything goes wrong. Also enable the Billing Alarm, which will keep you from extra spending.
• If you’re planning on sticking with AWS for a while, Reserved Instances can save you up to 30%.
• Track all changes by using a Version control system.
• Get even better performance by using a plugin dedicated to the database, page caching, and query.
• S3 and CloudFront are your tickets towards fast content delivery.
• Use a dedicated Aurora RDS to increase RDS performance.
• Back up! Sometimes, things beyond our control happen. It’s always essential to have a reliable backup strategy in place, and also a proper disaster recovery solution. One thing that makes AWS stand out is that its services can be very redundant among themselves, which makes backup much more manageable. Amazon also provides solutions for this problem, from different fronts.

In All…

While it may sound a little complicated, Amazon Web Services makes it very easy to build the proper architecture to function with WordPress. It’s just a matter of knowing what you’re crafting.
