![]() ![]() To support regulatory, performance, and data gravity requirements, the hyperscalers are now offering private cloud carveouts in public environments. In the past, choosing a hyperscaler meant picking public over private. Hybrid cloud eliminates reliance on any single cloud provider and allows for additional levels of flexibility in terms of capabilities, security compliance, etc. ![]() To create a true hybrid cloud architecture, you must set up communication or orchestration between the various deployments. ![]() Hybrid cloud often includes a combination of public cloud and private cloud, frequently in combination with some on-premise infrastructure. This is referred to as a hybrid cloud approach. Many organizations actually use a combination of several cloud environments. It is implemented on servers owned and maintained by the organization and accessed over the internet or through a private internal network.Ī private cloud environment gives you complete control over data and security in order to meet specific regulatory and other compliance requirements (e.g., HIPAA for healthcare, GDPR, GxP for Pharma, etc.). This cloud model is great for organizations concerned about sharing resources on a public cloud. Other cloud providers include IBM and Oracle. The big four hyperscalers, collectively referred to as MAAGs, are: Microsoft (Azure), Amazon (Amazon Web Services or AWS), Alibaba (Alicloud), and Google (Google Cloud). The largest cloud service providers with data centers that enable massive scaling are called hyperscalers. A shared public cloud has many organizations (or tenants) sharing the same infrastructure. Here's a primer on how they work and what they mean for your business.Ĭonnecting to a public cloud means using an internet connection to access computing resources hosted on data centers managed by a third-party cloud service provider, rather than owning and maintaining these resources on-premise. When a company is considering its cloud migration strategy, it must consider both factors. The next element is the service category-Saas (Software as a Service), Paas (Platform as a Service) and Iaas (Infrastructure as a service). ![]() The first thing to consider is the deployment model-public cloud, private cloud, hybrid cloud, and multi-cloud. But where does all this data actually live and who runs it?Ĭloud computing can be deployed in different ways depending on what services a business needs. We've established that most of us are already using cloud technology in some form or another. An organization can scale its resource usage levels up or down quickly and easily as needs change. So, rather than creating a copy of the application for each user, several users, or "tenants" can configure the application to their specific needs.Ĭloud platforms are elastic. This means a single application is shared among several users. Services can be requested and provisioned quickly, without the need for manual setup and configuration.Ĭloud often uses the multi-tenancy model. Think about how a utility company meters how much water, electricity, or gas is used and charges based on consumption. With a public cloud environment, users "plug into" the data and applications via an internet connection giving anytime, anywhere access.Ĭloud is often pay-as-you-go, where you only pay for what you use. There are five key characteristics of a cloud computing environment, as defined by the National Institute of Standards and Technology (NIST): Instead of organizations having to make major investments to buy equipment, train staff, and provide ongoing maintenance, some or all of these needs are handled by a cloud service provider. So, what exactly is it?Ĭloud is a model of computing where servers, networks, storage, development tools, and even applications (apps) are enabled through the internet. Now, many people and organizations refer to it as 'THE cloud' but it's not a single entity, and it doesn't exist in just the one place. When the internet was in its infancy the word 'cloud' was used as a metaphor to describe how the complex telephone networks connected. ![]()
