• Improving security in applications and data modernization
• Allowing developers to add cognitive capabilities
• Creating spatially aware mixed reality experiences in mobile applications.

Plus, SaaS offerings typically include robust data protection features, such as built-in and one-click backup recovery capabilities and the ability to store backups in different geographic regions.

Cloud Deployment Models

Just like there are different types of buildings — residential, commercial, and industrial — there are different deployment models in the realm of cloud computing. These include:

Each model offers varying levels of control, privacy, and resource sharing, catering to different organizational needs and preferences.

Public Cloud

Public cloud which are operated by third-party cloud service providers, is akin to a commercial building with various businesses renting spaces. It offers a range of services and resources, available to the general public over the Internet.

This model provides organizations with improved scalability, flexibility, and cost-effectiveness.

Private Cloud

Private cloud, on the other hand, is like a custom-built office space designed for a single organization. It offers enhanced security and better control over computing resources, which can be customized to meet specific business needs.

For organizations with stringent security and privacy standards, such as those in finance, healthcare, and government, private clouds facilitate regulatory compliance with dedicated physical machines and private network connections.

Hybrid Cloud

Hybrid cloud combines on-premises infrastructure (or private clouds) and public clouds. It’s like having a head office in a private building and branches in commercial spaces. This model allows data and applications to be shared between them, providing flexibility and the best possible utilization of resources.

Multi-Cloud

A multi-cloud approach involves utilizing multiple cloud computing and storage services in a single architecture to optimize performance and cost efficiency. It can be compared to a business having offices in different buildings, each offering unique advantages and services. Adopting a multi-cloud strategy can prevent vendor lock-in, thus providing enhanced flexibility and a wider choice among various cloud services.

Cloud Migration Strategies

Just as there are multiple paths to a destination, there are multiple strategies to migrate to the cloud. These include:
