Public cloud This is a model in which a provider gives users access to computing resources over the public internet. It is multi-tenant: users share a pool of virtual resources, which the provider allocates among individual tenants through a self-service interface. In a public cloud, multiple tenants can run CPU instances on a shared physical server at the same time, while their data remains separate.
Because many customers share resources, providers offer their services at a more low cost compared with maintaining their own infrastructure.
Benefits of public cloud: - simple and fast scalability - the ability to instantly or automatically add computing power in response to unexpected traffic spikes; - savings- paying only for the resources and services actually used, without having to fund deployment and maintenance of on-premises IT infrastructure; - easy setup- rapid deployment of new resources without purchasing hardware or setting up physical infrastructure.
Private cloud This is a computing model in which resources are available to only one customer. Private clouds can be hosted on leased infrastructure in an external data center, on premises in the organization’s own data center, or on the provider’s infrastructure. In a private cloud greater control over security and resource configuration, than in the public cloud.
Companies can configure it to match their data protection needs using firewalls, virtual private networks, data encryption, keys API and other custom security measures.
Benefits of private cloud: - high control over IT resources using configurations maintained by members of the internal IT team; - customization hardware and software based on business needs; - high transparency and access controlby keeping sensitive data and applications behind private firewalls that reduce the attack surface. Hybrid cloud It combines on-premises infrastructure, public cloud, and private cloud.
The result is a unified, flexible, and integrated IT infrastructure. It makes it possible to use the scalability and cost advantages of public clouds while maintaining control over mission-critical applications and sensitive data through private infrastructure. In companies using hybrid cloud environments to monitor and optimize production, production line efficiency increased by 35%.
Implementing a hybrid cloud architecture includes: - configuring workload portability across all cloud environments; - automating workload deployment in the cloud environment best suited to a specific business goal. Hybrid cloud supports microservices, an architectural approach in which one application consists of many loosely coupled and independently deployable components or services. Microservices help teams build applications once and run them across all types of clouds.
For example, Uber uses a microservices architecture to rapidly develop and release its services. Hybrid cloud helps work with edge devices and Internet of Things devices thanks to flexible compute, networking, and cloud storage resources. It makes it possible to collect information, analyze data, and perform predictive maintenance with low latency and no downtime.
Benefits of hybrid cloud solutions: - flexibility- distributing workloads according to business needs; - security- protection of sensitive data within private cloud infrastructure; - cost efficiency - agile methodologies help speed up application development and shorten time to market; - digital transformation - the ability to process big data and use artificial intelligence and machine learning algorithms.
59% of technology leaders use hybrid security solutions. This allows them not to depend on a single vendor's security protocols.
