Each organization must evaluate cloud offerings for itself to see what best fits its needs. The CSP has to ensure that no data can be retrieved in any way from any media after termination of the cloud service. Though a public cloud deployment is suitable for most uses that are nonsensitive, migrating sensitive, mission critical, or proprietary data into any cloud environment that is not certified and designed for handling such data introduces high risk. Basic guidelines are described in Section 5. Hybrid cloud In a hybrid cloud, an organization makes use of interconnected private and public cloud infrastructure. Solutions that are cloud provider agnostic could potentially benefit a company financially, as it would be easier to migrate their workloads to a different provider that offers better pricing. Figure 1.1 summarizes the computing architecture evolution. Cloud Deployment Models – Public, Private and Hybrid Cloud In this cloud training tutorial, I’m going to cover the four cloud deployment models as defined by NIST. Operates under a shared responsibility model. There are three different ways to deploy cloud services: on a … Cloud deployment models indicate how the cloud services are made available to users. Thus, the cloud computing deployment models and strategy are first and foremost classified according to the location. Can be perceived as complex when attempting to leverage traditional tools for governance and compliance. From a compliance standpoint, storing or transferring data in regions that are outside of the company’s country of origin could be subject to differing regulatory requirements. Meaning, the provider is responsible for the “security of the cloud” and customers are responsible for “security in the cloud” (applications they deploy and configuration of services they leverage). These companies tend to have something in common—they’re using containers and container tools like Kubernetes. Another characteristic of the public cloud deployment model is that customers will never see, know, or have physical access to the hardware running said services. Multitenancy risks: The shared nature of public cloud environments increases security risks, such as unauthorized viewing of data by other customers using the same hardware platform. Be sure you understand what it is you and your organization require before you embark on logging all your log data to the cloud. Let’s take a closer look at the advantages and disadvantages associated with the hybrid cloud deployment model. Based on the strategy and the cloud policy, the contracts with the CSP as well as with the ISPs have to be negotiated. Also, the community cloud deployment model is a compromise solution. These models differ in terms of management, ownership, access control, and security protocols. Hello and welcome to this lecture where I shall explain some of the different deployment models used when adopting Cloud technology. That means you won‘t get the full benefits of either … In summary, a multi-cloud deployment model is all about choices. Typically within Cloud computing, there are three different Cloud … Different Types Of Cloud Computing Deployment Models Most cloud hubs have tens of thousands of servers and storage devices to enable fast loading. Now a vast array of service models is available. It is important to point out that they don’t have to compromise and choose a single model. The private cloud is a cloud model where a single organization uses the cloud.The organization or a third party could own, manage, and operate the cloud. 3. Thomas Kemmerich, ... Carsten Momsen, in The Cloud Security Ecosystem, 2015. The subtasks of the planning phase shall include as a minimum the following points: Definition of required cloud deployment model, Definition of the CSP (call for tender or scan the Internet), Virtualization software (vendor, type, version, upgrade cycle, …), Flexibility in upgrading or keeping the version level in accordance also to other cloud customers, Definition of the basic rollback scenario. When an organization might want to move systems with older operating systems and Microsoft Office … A public cloud deployment model offers companies the ability to consume highly available and scalable services hosted on shared infrastructure. SIEM in the cloud: MSSPs have supported this model for years. Definition of responsibilities during the whole migration process from definition of concepts—testing—transfer—takeover, etc. The operations phase is a more or less steady-state situation where the cloud customer mostly has to take care that the quality of the IT-Service provision is sufficient. Private cloud True to its name, a private cloud is typically infrastructure used by a single organization. The gray strategy offers, on the one hand, the possibility to negotiate regularly new condition with the actual CSP. But all assumed advantages of using a CSP would be lost. Changes to an operational environment are inevitable as a system undergoes routine maintenance. These are typically grouped as services and made available either for free or charged via subscription models or based on usage. However, this is only possible if a company has the ability to run and manage a complex environment. This helps reduce vendor lock-in and improve reliability. Typically, these legacy applications require adapters and wrapper software to make them accessible via Web services. To take advantage of cloud computing, legacy applications such as those developed using mainframe client/server technologies need to be adapted or migrated to modern languages and APIs so that they can interact with other applications regardless of where they are deployed. Also, make sure you understand your responsibility when it comes to legislative and regulatory compliance when operating in a cloud environment.
