Top Cloud Computing Companies


The purpose of this article is to provide you with a guide for cloud computing and the top cloud computing companies.

Here you will find could definitions and types, IaaS and SaaS basics, and advantages and benefits of using cloud solutions.

The list of the best cloud computing and hosting providers will provide you with the information you can use for comparison between them.

What is cloud computing?

Cloud computing provides shared resources and data to computers and other devices on demand.

It means that the cloud is something “outside” your organization and you actually “rent” storage, processing power or software.

Usually, cloud computing companies are third party vendors which have a powerful data center or well-developed software.

The clients of their services are companies which need various services – additional storage, web hosting, new environments, more security, server performance, etc.

Cloud benefits

Cloud computing offers a wide range of advantages.

Flexibility – you can “rent” small cloud and upgrade it later. It grows when your business grow.

Cost – CAPEX (capital expenditure) becomes OPEX (operational expenditure). It is excellent for investment planning.

Maintenance – Each cloud computing provider offers some level of maintenance. It means you will need fewer system admins or engineers.

Scalability – Most of the cloud computing providers offers automatical scalability options. It means that if you have peak performance, the data center provides with more resources.

Access – In most cases, you can access from everywhere if you have user rights.

Security – Cloud providers usually have an excellent level of security.

Cloud Services

There are 3 main types of cloud services – IaaS, SaaS and PaaS.

IaaS – Infrastructure as a Service is the most common type. This article is written mainly for it. IaaS is pure computing power and can be described as “renting hardware”.

It means that you can “rent” virtual machine with CPU, RAM and storage for hosting your data. You can see the example offer.

Of course, this is not all. The cloud computing providers offer firewalls, public and private IPs, load balancers, network devices, and more.

SaaS – Software as a Service allows you to “rent” software system or some of its module. It has many advantages – the software is actually working, it has maintenance, it is usually stable and   of course, you can rent minor access or modules. Which means that you can actually test it before starting implementation. The drawback is that not each required change can be implement is that not each required change can be implemented or at least implemented on a reasonable price.

In fact, many companies offer both on-premise and SaaS types of pricing modules.

PaaS – Platform as a service offers access to platforms as databases, application servers, development tools, and etc.

Cloud Types

There are 3 majoed or at least implemented on a reasonable price.

The drawbackr types of clouds supported by cloud computing companies:

Private – all physical infrastructure is used by one organization only. Usually, it requires more efforts but from the other hand, you have full control.

Public – these are the classical clouds and they are rendered over a network that is open for public use. Usually, 3-rd party vendors have their own databases which are accessed via the Internet to the user rights.

Hybrid – these clouds have both private and public elements. For example private cloud with some servers in the  company’s office with VPN connection to the public cloud resources.

Companies Requirements

Before you select your cloud computing provider, you need to consider two major items:

  1. Your business need
  2. And need-based requirements.

First, define why do you need a cloud – for additional storage, for more power, for an additional environment, for hosting, for security, etc. Obviously, there is no single company on the market which is best in all the above aspects. So defining your business need and goal is a crucial element in comparison and selection.

Second, there is a list of requirements which may arise. Here are some examples:

  • Cloud Management software, web-based and mobile access
  • Terminal Access and APIs
  • Range of resources – CPU, RAM, hard disk space, operating systems
  • Transfer In and Out options
  • Range of IPs
  • Load Balancing services
  • Encrypted storage
  • VPNs and Firewalls
  • Automatic failover to other servers
  • Automatic scalability in rush hours
  • Dedicated servers and collocation options
  • Maintenance 24/7

OK, there are much more. But one good cloud computing provider should have at least 2/3 of the above requirements. Anyway, it is up to you to decide which requirements are most important.

Major Cloud Computing Companies

Here is a list of cloud providers specialized in computing, but most of them have hosting and storage options also.

So let’s start with the big “fishes”:

Microsoft Azure

This is one of the best cloud service providers. For obvious reasons – it provides tons of cloud features.

From virtual machines to pure storage, from SaaS services to big data, gateways, networks, apps, etc.

Microsoft Azure provides 50 cloud services.

And what about cloud computing?

It is excellent – you have high availability, autoscaling, Azure Software Development Kit  integrated with Visual Studio, monitoring software, alerts, one of the best CPU, RAM and storage options available.

So you can have all of the cloud services – IaaS, PaaS and SaaS, integrated and stable with tons of MS apps and integration options (APIs, VPN, etc).

Downside – almost none. The storage is not encrypted and pure web-hosting is kind of expensive. But overall, Microsoft Azure is one of the best and most reliable cloud service providers.

More information – on Microsoft Azure website.

Amazon Web Services

Amazon is one of the best cloud computing companies around. In fact, it offers a full range of infrastructure, platform,  and software as a service.

And when it comes to cloud computing options Amazon shines. It offers virtual servers, auto-scaling, load balancing, especially good when it comes to big data. You can “rent” very impressive amount of CPU, RAM and storage power plus Oracle database. So if you need big data you can trust it.

Of course, this is not all – Networking options are impressive. You can have a virtual private cloud, DNS, all types of IP, APIs, etc.

Security options are excellent. Amazon Web Services are PCI DSS compliant, has ISO/IEC 27001 and EU Directive 95/46/EC. Firewalls are impressive and there are useful VLAN and VPN options.
