What is AWS cloud hosting?
AWS (Amazon Web Services) is Amazon's complete cloud computing platform, which comprises infrastructure as a service (IaaS), platform as a service (PaaS), and packaged software as a service (SaaS) products. AWS services may provide a company with resources like computational power, database storage, and content distribution.
For handling its online retail activities, Amazon.com created Amazon Web Services in 2006 as an extension of its internal infrastructure. AWS was one of the first firms to provide a pay-as-you-go cloud computing model, which expands to meet customers' needs for computation, storage, and throughput.
AWS provides a variety of tools and solutions for businesses and software developers that may be utilised in data centres throughout the globe. AWS services are available to government agencies, educational institutions, charities, and private businesses.
AWS is divided into numerous services, each of which may be customised in a variety of ways depending on the requirements of the user. For an AWS service, users should be able to access configuration choices and specific server mappings.
Where are AWS cloud servers located?
There are over 200 fully-featured services accessible from data centres all around the globe, and the AWS Global Cloud Infrastructure is the most secure, comprehensive, and trustworthy cloud platform available. You don't have to worry about deploying application workloads throughout the globe in a single click, or about designing and deploying bespoke applications closer to your end-users with latency in the single-digit millisecond range, since AWS can assist.
As a result of its millions of active customers and tens of thousands of partners, Amazon Web Services (AWS) has the world's largest and most lively ecosystem. The AWS cloud platform is being used by clients from almost every industry and organisation size to execute virtually every potential use case, including start-ups, small enterprises, and public sector organisations.
What is the basic architecture for AWS?
This is AWS EC2's fundamental structure, with EC2 standing for Elastic Compute Cloud. EC2 allows customers to utilise virtual computers in a variety of configurations, depending on their needs. It has a variety of setup choices, server mapping, price options, and so on. In the AWS Products section, we'll go through them in further depth.
Architecture
Note on the architecture: S3 stands for Simple Storage Service in the diagram above. It lets users perform API calls to save and retrieve different sorts of data. It is devoid of any computational components. In the AWS products section, we'll go over this issue in further depth.
Load Balancing
Load balancing refers to the distribution of hardware or software loads among web servers, which improves the server's and application's performance. The diagrammatic depiction of AWS architecture with load balancing is shown below.
In classic web application designs, a hardware load balancer is a standard network device.
Elastic Load Balancing is a service provided by AWS that distributes traffic to EC2 instances among various accessible sources and allows for dynamic addition and removal of Amazon EC2 hosts from the load-balancing cycle.
Elastic Load Balancing may dynamically increase and decrease load-balancing capacity in response to traffic demands, as well as provide sticky sessions for more complicated routing requirements.
CloudFront
It is in charge of content delivery, i.e. how a website is delivered. Using a worldwide network of edge points, it may hold dynamic, static, and streaming content. Requests for material from the user are automatically sent to the closest edge point, resulting in improved performance.
Other Amazon Web Services, such as Amazon S3 and Amazon EC2, are tailored to operate with Amazon Cloud-front. It also works with non-AWS origin servers and saves the original files in the same way.
There are no contracts or monthly obligations with Amazon Web Services. We just pay for the amount of material we distribute via the service.
Elastic Load Balancer
It's utilised to distribute traffic to web servers, resulting in better performance. Elastic Load Balancing is an AWS service that distributes traffic to EC2 instances across many available zones and allows for the dynamic addition and removal of Amazon EC2 hosts from the load-balancing cycle.
The load-balancing capability of Elastic Load Balancing may dynamically increase and decrease in response to traffic circumstances.
Security
Security groups, akin to an incoming network firewall, are a feature of Amazon's Elastic Compute Cloud (EC2) that allows us to designate which protocols, ports, and source IP ranges are permitted to reach our EC2 instances.
One or more security groups may be allocated to each EC2 instance, with each group routing the necessary traffic to each instance. Specific subnets or IP addresses may be used to create security groups that restrict access to EC2 instances.
Elastic Caches is a web service from Amazon that controls the memory cache in the cloud. Cache plays a crucial role in memory management, as it reduces strain on services and increases efficiency and scalability on the database layer by caching frequently used data.
Amazon RDS
Amazon RDS (Relational Database Service) is a database engine that works similarly to MySQL, Oracle, and Microsoft SQL Server. With Amazon RDS, you may use the same queries, apps, and tools.
It automatically updates database software and handles backups according to the user's preferences. It also allows for recuperation at a certain moment in time. We don't have to make any upfront investments, and we merely pay for the resources we utilise.
Using EC2 Instances to host RDMS
Amazon RDS enables customers to install and operate RDBMS (Relational Database Management Systems) such as MySQL, Oracle, SQL Server, DB2, and others on an EC2 instance.
Similar to network-attached storage, Amazon EC2 makes use of Amazon EBS (Elastic Block Storage). All data and logs from EC2 instances should be saved to Amazon EBS volumes, which will remain accessible even if the database server fails.
Amazon EBS volumes automatically offer redundancy inside the availability zone, boosting basic disc availability. Furthermore, if the storage is insufficient for our database's demands, more space may be added to improve the speed.
Using Amazon RDS, the storage is managed by the service provider, leaving us to concentrate only on data management.
Backups and storage
The AWS cloud offers a variety of storage, access, and backup options for web application data and assets. The Amazon S3 (Simple Storage Service) offers a simple web-services interface for storing and retrieving an unlimited quantity of data from anywhere on the internet at any time.
Data is stored in Amazon S3 as objects inside buckets, which are resources. The bucket may hold as many things as the user desires, and the user can read, write, and remove objects from it.
Database partitions and application logs, for example, are good candidates for Amazon EBS since they need to be accessible as block storage and need durability beyond the life of the operating instance.
Amazon EBS volumes can be striped for greater volumes and better performance, and they can be maximum up to 1 TB. Provisioned IOPS volumes are optimised for database applications that need high storage performance and consistency.
Currently, Amazon EBS supports up to 1,000 IOPS per volume. We may stripe numerous volumes together to provide an application thousands of IOPS per instance.
Auto Scaling
The distinction between AWS cloud architecture and conventional hosting is that AWS can dynamically grow the web application fleet to address fluctuations in traffic on demand.
Traffic forecasting methods are often employed in the conventional hosting paradigm to provide hosts ahead of predicted traffic. In AWS, instances may be created on-demand based on a set of triggers for scaling out and back in the fleet. Amazon AutoScaling allows you to establish server capacity groups that may increase or decrease based on demand.
Is AWS public or private cloud?
With the widespread acceptance of cloud computing, three basic cloud models have emerged: private, public, and hybrid clouds. The sections that follow look at which models are best for certain workloads.
The Amazon Web Services (AWS) public cloud delivers public cloud services such as the Amazon Elastic Compute Cloud (Amazon Amazon EC2), which provides infrastructure and services through the internet and is housed in an AWS Region (for example, Canada Central). Although the infrastructure and services are provided from a distant location, the consumer has little control over where the service is hosted and has minimal visibility. They may, however, access such services wherever and whenever they need them. Low cost of ownership, automated deployments, scalability, security, recovery, and dependability are all benefits of the AWS public cloud. The AWS public cloud is ideal for the following tasks:
- Storage of data
- Archiving of data
- Hosting for Applications
- Web tiers that are latency-sensitive or mission-critical
- Microsite and application hosting on demand
- For big applications, an auto-scaling environment is available
Private cloud
A private cloud, as the name implies, is a cloud infrastructure that is only used by one company. The cloud is either solely owned, managed, and operated by the organisation, or by a third-party provider, or both. The infrastructure is supplied on-premise utilising a virtualization layer in this cloud approach (for example, VMware). Private cloud environments provide more configurability for any application, as well as support for older apps that are experiencing performance challenges in the public cloud.
While the private cloud provides the most control and security, it necessitates the business purchasing and maintaining the complete infrastructure as well as acquiring and maintaining the necessary skills. As a result, the private cloud is much more costly. It makes sense to use a private cloud for the following reasons:
The public cloud fails to meet strict security, latency, regulatory, and data privacy requirements.
Those who work in highly regulated environments and need data to be stored quietly and securely:
- Organisations have the financial resources to cover the expenditures
- Media firms, for example, need high-performance access to a file system
- Hosting apps with well-defined use patterns and modest storage requirements
- Organisations need to be more adaptable, configurable, and flexible
- Data and programmes that are vital to the company are hosted on this server
Hybrid
When a company wants to make use of the cloud for efficiency and cost savings while simultaneously maintaining on-site security, privacy, and control, it turns to the hybrid cloud, which is essentially a cross between public and private clouds. At least one private and one public cloud are used in the hybrid cloud.
A hybrid cloud may also be made up of many private and public clouds, as well as a large number of active physical or virtualized servers that aren't part of the private cloud. organisations may use the hybrid cloud to retain each business element in the most efficient cloud format feasible. organisations must, however, manage numerous security platforms and characteristics with the hybrid cloud, as well as guarantee that all cloud assets can interact fluidly with one another.
The following scenarios are best served by a hybrid cloud:
- Large enterprises need the flexibility and scalability that the public cloud provides.
- Customer interactions may be housed in the public cloud, while corporate data can be stored in the private cloud, for organisations that provide services to vertical markets.
- Organisations that want more operational scalability and flexibility. Mission-critical data may be stored in the private cloud, while application development and testing can be done on the public cloud for them.
- Organisations must continually assess their cloud infrastructure, whether public, private, or hybrid, to guarantee that the cloud provides outcomes in today's dynamic and more complicated business environment. Because each of these cloud models has various security and administration requirements, businesses must carefully choose their cloud application candidates so that they may stimulate innovation and enhance agility by using their IT resources.
Is there AWS cloud hosting specifically for WordPress?
Yes! EC2 is Amazon Web Services' cloud computing platform, which enables you to operate virtual computers and web applications such as WordPress.
Is there AWS cloud hosting for Drupal?
AWS is a suitable platform for running Drupal workloads because it offers flexible computing, storage, and database capabilities. AWS provides a comprehensive range of services and tools for delivering mission-critical corporate workloads on its highly dependable and secure cloud infrastructure.
Drupal provides a highly flexible, scalable, and high-performance platform for pay-as-you-go online content management when combined with AWS as the underlying infrastructure.
Is AWS good for the public sector?
The UK public sector is able to take advantage of developing technology as more firms migrate to the cloud. These organisations can deliver more cost-effective, accessible citizen services to reach more people and achieve good change throughout the country by emphasising innovation. The opportunities of digital transformation are expanding by the day, thanks to the AWS Cloud. Voice, open data, machine learning, and other technologies may help public sector enterprises enhance residents' lives more swiftly.
LocalGovDrupal on AWS
LocalGov Drupal is built on the Drupal 9 platform. The publishing platform was created by and for councils. LocalGov Drupal is a publicly owned asset that enhances the digital experience of citizens, improves service results, and saves money.
LocalGov Drupal is now being used by 24 councils in the United Kingdom, with more on the way.

Benefits of AWS hosting
The following are some of the most obvious benefits of AWS hosting:
- There are no physical network devices required
- For AWS applications, network equipment such as firewalls, routers, and load-balancers are replaced with software solutions rather than physical devices.
- There are a variety of ways for ensuring high-quality software solutions. Choose among Zeus, HAProxy, Nginx, Pound, and other load balancing options. OpenVPN, OpenSwan, Vyatta, and other VPN clients may be used to create a VPN connection.
- There are no security issues
AWS offers a more secure paradigm in which each server is password-protected. Security groups are built-in Amazon EC2 for each kind of host in the architecture, and a wide range of basic and tiered security models may be developed to permit minimal access across servers inside your architecture, depending on your needs.
Data centre accessibility
EC2 instances are readily accessible across the majority of AWS region availability zones, and they offer a paradigm for deploying your application across data centres for high availability and dependability.
