Manage Cloud & Data Center Infrastructures
Take advantage of the scalability and agility of the cloud without having to maintain your own expertise or personnel resources. We manage individual IaaS offerings for you, especially from the large hyperscalers Azure, VMware cloud Services, AWS or Google - or also from our datacenter (private cloud). And we orchestrate your entire IT infrastructure, even if you want to combine different cloud offerings or integrate your existing IT.
What Is a Data Center?
Data center is a physical facility that organizations use to house their critical applications and data. A data center's design is based on a network of computing and storage resources that enable the delivery of shared applications and data. The key components of a data center design include routers, switches, firewalls, storage systems, servers, and application-delivery controllers .
Key Concepts
Data Center Infrastructure
Data center infrastructure refers to all of the physical resources and components that comprise and support a data center. A data center infrastructure may include servers, computers, networking equipment such as routers or switches, security such as firewall or biometric security system, storage such as storage area network (SAN) or backup/tape storage, and data center management software/applications. This category can also include non-computing resources like power and cooling devices such as air conditioners or generators, physical server racks/chassis, and cables, as well as internet backbone.
Physical Components of Data Center Infrastructure
Physical components of data center infrastructure refer to the touchable or physical parts, also the most important component for designing data center networks. In this sense, they include components that are core to the operations of the facility, such as computers, switches, and servers, and infrastructure in place designed to support that core IT infrastructure, such as cooling equipment, electricity, foundation, etc.
On-Premises
An on-premises data center or on-prem refers to a private data center that companies house in their own facilities and maintain themselves. To put it simply, a company's software is installed and controlled locally on its own computer servers. Please notice that an on-premises data center is not equal to a private cloud, because the latter can be on premise or hosted in a third party's data center. It means that on-prem infrastructure can be used to run private clouds where computing resources are virtualized in much the same way as those of public clouds. But private clouds can also be run on third-party cloud providers
.
Types of Data Centers
Many types of data centers and service models are available. Their classification depends on whether they are owned by one or many organizations, how they fit (if they fit) into the topology of other data centers, what technologies they use for computing and storage, and even their energy efficiency. There are four main types of data centers:
Enterprise data centers
These are built, owned, and operated by companies and are optimized for their end users. Most often they are housed on the corporate campus.
Managed services data centers
These data centers are managed by a third party (or a managed services provider) on behalf of a company. The company leases the equipment and infrastructure instead of buying it.
Colocation data centers
In colocation ("colo") data centers, a company rents space within a data center owned by others and located off company premises. The colocation data center hosts the infrastructure: building, cooling, bandwidth, security, etc., while the company provides and manages the components, including servers, storage, and firewalls.
Cloud data centers
In this off-premises form of data center, data and applications are hosted by a cloud services provider such as Amazon Web Services (AWS), Microsoft (Azure), or IBM
Benefits
A cloud data center reduces both hardware investment and the ongoing maintenance cost of any infrastructure. It gives greater flexibility in terms of usage options, resource sharing, availability, and redundancy.

Cloud Computing
When people speak of cloud computing, usually they’re referring to traditional or public cloud, a model in which a third-party service provider hosts computing resources for a company. Public cloud, as its name suggests, is a multi-tenant environment, meaning that these computing resources are shared by multiple individuals or companies, with the data of each secured by state-of-the-art encryption.
Cloud & IT Services
What Is Cloud Computing?
Digital transformation is helping companies rapidly drive efficiency, agility, and connectivity as they use technology to transform their business processes into something easier, faster, and more secure, flexible and profitable. Cloud computing technology is a cornerstone to digital transformation.
What are the benefits of cloud computing?
Cloud computing offers companies convenient models to access infrastructure, platforms, and software offerings on a pay-as-you-go basis. With cloud computing, companies are freeing up capital, streamlining IT maintenance, modernizing and scaling business approaches, building security and flexibility into services and solutions, helping customers in new ways, and growing their business in ever-changing market conditions.
Types of cloud computing deployment models
Private cloud
The private cloud model refers to cloud computing resources used exclusively by a single business or organization. A private cloud can be located in your on-site data center or hosted in the cloud by a service provider.
Public cloud
When an organization deploys a public cloud model, all hardware, software, and supporting infrastructure is owned and managed by a service provider, which is delivered exclusively over the Internet. You access these services and manage your account through a web browser.
Hybrid cloud
A hybrid cloud computing model combines public and private clouds to share data and applications. Hybrid clouds connect infrastructure and applications between cloud-based resources with existing resources not located in the cloud. This approach gives your business greater flexibility and deployment options.
Types of cloud computing services
Cloud computing services offer convenient, pay-as-you-go models that eliminate costly expenditures and maintenance. Cloud providers host a choice of infrastructure, platform, and software offerings on-site that they "rent," giving your organization the flexibility to turn cloud computing services up and down according to your changing requirements.
Infrastructure-as-a-Service (IaaS)
Think of IaaS as the building blocks for cloud-based IT. In this model, a cloud provider hosts infrastructure components that are traditionally located in on-premises data centers. For example, servers, storage and networking hardware, along with the hypervisor (virtualization layer), usually reside on-premises. With IaaS, your organization can choose when and how you want to administer workloads, without needing to buy, manage, and support the underlying infrastructure. IaaS gets your infrastructure up and running quickly, with a pay-as-you-go model.
Platform-as-a-Service (PaaS)
PaaS builds on the IaaS model, but is usually specific to hardware and software tools for application development. Cloud providers, in addition to providing infrastructure components, also host and manage operating systems and middleware that your developers need to create and run applications. PaaS offers an on-demand, pay-as-you-go model.
Software-as-a-Services (SaaS)
With SaaS, cloud providers host and manage an entire infrastructure, as well as end-user applications. When your company chooses a SaaS model, you do not need to install anything; your users will be able to log in and begin immediately using the cloud provider's application running on their infrastructure. SaaS frees you to think only about how your business will use that software, not how to maintain it. SaaS is available on demand or by subscription.
