Understanding Hybrid Cloud

Hybrid cloud architecture brings together private and public cloud services into a unified system, making management and operations more straightforward. By leveraging advanced software, organizations can easily move workloads between their physical data centers and public cloud networks.

Many businesses incorporate Infrastructure as a Service (IaaS) platforms like Microsoft Azure, Google Cloud, and AWS into their hybrid setups. While this model provides significant benefits in terms of scalability and flexibility, it also introduces unique challenges. Security concerns and the complexities of data management and integration can create hurdles that organizations need to navigate carefully to maintain a robust hybrid cloud infrastructure.

Cloud Service Models

Organizations, ever under innovation, are breaking loose from the conventional cloud computing service models into newer options best suited to their needs. The National Institute of Standards and Technology (NIST) defines several main cloud service models as underlining the core of today’s cloud technology:

• Software as a Service (SaaS): This type avails users of the application over the web with providers taking on all aspects of application management and delivery over the internet with no local installation.
• Infrastructure as a Service (IaaS): IaaS resorts to scalable computing resources to assist people in acquiring the hardware parts from the providers who deliver their service with the convenience of not having to maintain physical infrastructure.
• Platform as a Service (PaaS): PaaS provides a platform within which a developer can design, build, and deploy his or her applications while the complexity of the infrastructure under it is abstracted by the process.
• Data as a Service (DaaS): DaaS ensures effective database management through safe data access that supports critical business operations.
• Security as a Service (SECaaS): Implemented to deliver core security solutions in hybrid cloud environments, in which it relies on cloud-based platforms to address some of the security requirements.

These service models help organizations maximize their benefits from cloud computing while addressing their unique operational challenges effectively.

Hybrid Cloud Security Challenges

Hybrid cloud environments will pose some security challenges that the organizations need to face:

• Complex management: Maintaining constant security policies in on-premises and cloud environments could be complex, thus opening holes.
• Visibility: The ability to detect threats and respond sometimes could not be helpful to threat detection where full visibility into those infrastructures is lacking.
• Misunderstanding the shared responsibility: In shared cloud environments, companies can be confused about their responsibility and the cloud providers’, thus leaving protection gaps.

• Data Protection: Sensitive data and governance provisions need to be protected at the same time.
• Legacy Tools: Security solutions are somewhat outdated and lack suitability for hybrid cloud environments.
• Higher Attack Surface: Hybrid Configurations cause entry points for cyber attacks with a higher count, thus increasing security risk.
