What is a Community cloud and how does it work?

A community cloud is a shared in­fra­struc­ture ac­cess­ible to various par­ti­cipants, typically companies, au­thor­it­ies, or or­gan­isa­tions. It may involve all or some parties sharing their in­fra­struc­ture, or a single or­gan­isa­tion providing its resources to others. The goal is to foster net­work­ing, data exchange, and col­lab­or­a­tion while main­tain­ing high security standards.

How does a community cloud work?

The community cloud operates on a similar principle to other (public) cloud solutions, where a third-party provider offers services and software either for free or for a fee. It provides resources like servers, storage, databases, software, and analytics services. However, unlike a public cloud, access in a community cloud is re­stric­ted to certain users, and specific guidelines govern service usage. It also functions like a private cloud in that it is client-capable, allowing for the addition of new members and scalable resources as needed.

The cloud can be provided in two ways. In one approach, several parties col­lab­or­ate to rent and configure server struc­tures according to their needs. Each or­gan­isa­tion offers its own services to other par­ti­cipants, with all parties agreeing on and adhering to common com­pli­ance re­quire­ments.

Al­tern­at­ively, a single par­ti­cipant converts its own private cloud in the data centre or via a provider into a community cloud and makes the services hosted there available to other selected in­ter­ested parties. In this case, the guidelines are usually defined and enforced by the host.

What are the most important ap­plic­a­tions?

There are many potential ap­plic­a­tions for the community cloud, even though it is less common than other forms of cloud computing. It is par­tic­u­larly useful where different in­di­vidu­als and groups col­lab­or­ate on joint projects or share the same services. For example, multiple companies can pool their expertise and resources, be­ne­fit­ing all parties and reducing costs. Ad­di­tion­ally, partners working together on a project may find a community cloud ad­vant­age­ous.

The solution is also fre­quently used by large or­gan­isa­tions with global networks, allowing for optimal co­ordin­a­tion. For instance, companies that rely on freel­an­cers can use the cloud to provide them with essential programs and access to server struc­tures and projects. Ad­di­tion­ally, full-time employees working from home or clients that you have long-term re­la­tion­ships with can access all relevant services through a community cloud.

What are pros and cons of the community cloud?

There are numerous ad­vant­ages and a few dis­ad­vant­ages as­so­ci­ated with using a community cloud.

Pros

• Scalab­il­ity: Larger resources can typically be quickly scaled up as needed.
• Security: Community clouds are con­sidered very secure, pre­vent­ing data loss and un­au­thor­ised access.
• Cost: Sharing costs among multiple parties reduces the financial burden on each par­ti­cipant.
• Net­work­ing: Col­lab­or­a­tion among different parties is sig­ni­fic­antly easier, which also optimises the execution of joint projects.
• Custom Access Control: Rights and re­spons­ib­il­it­ies can be tailored to the specific needs of each par­ti­cipant.
• Avail­ab­il­ity: Data avail­ab­il­ity is increased with a cloud solution, including community clouds.

Cons

• Effort: The effort required for con­fig­ur­a­tion and main­ten­ance is re­l­at­ively high.
• De­pend­ence: The success of such a solution depends on all par­ti­cipants. The principle can only work if everyone follows the rules and fulfills their re­spons­ib­il­it­ies, es­pe­cially con­cern­ing data security.

What al­tern­at­ives are there for the community cloud?

If the community cloud model doesn’t suit your needs, there are three al­tern­at­ives that can help you with vir­tu­al­isa­tion:

• Public Cloud: This solution offers services openly over the internet. There are both free and paid providers.
• Private Cloud: This refers to an internal cloud that is ac­cess­ible only to selected users.
• Hybrid Cloud: This option allows you to store data partially in a private or public cloud and the rest in a tra­di­tion­al data centre.
