Cyber Security | Cloud services

Fueled by more sophisticated adversaries, modern threats are more pervasive and doing more damage, faster. Most organizations think they are protected once everything is on the cloud – public could. The public cloud refers to the cloud computing model in which IT services are delivered via the internet, means that you are sharing cloud computing resources with many other organizations. Lack of cost control. The total cost of ownership (TCO) can rise exponentially for large-scale usage, specifically for midsize to large enterprises. Lack of security. Public cloud is the least secure, by nature, so it isn’t best for sensitive mission-critical IT workloads. Minimal technical control. Low visibility and control into the infrastructure may not meet your compliance needs.

Private Cloud Solution

In the private cloud, you’re not sharing cloud computing resources with any other organization. The computing resources are isolated and delivered via a secure private network, and not shared with other customers.

Private cloud is customizable to meet the unique business and security needs of the organization. With greater visibility and control into the infrastructure, organizations can operate compliance-sensitive IT workloads without compromising on the security and performance previously only achieved with dedicated on-premise data centers

The private cloud is best suited for:

  • Highly regulated industries and government agencies

  • Sensitive data

  • Companies that require strong control and security over their IT workloads and the underlying infrastructure

  • Large enterprises that require advanced data center technologies to operate efficiently and cost-effectively

  • Organizations that can afford to invest in high performance and availability technologies

The most popular benefits of private cloud include:

  • Exclusive environments. Dedicated and secure environments that cannot be accessed by other organizations.

  • Custom security. Compliance to stringent regulations as organizations can run protocols, configurations, and measures to customize security based on unique workload requirements

  • Scalability without tradeoffs. High scalability and efficiency to meet unpredictable demands without compromising on security and performance

  • Efficient performance. The private cloud is reliable for high SLA performance and efficiency.

  • Flexibility. The private cloud is flexible as you transform the infrastructure based on ever-changing business and IT needs of the organization.

Hybrid cloud

The hybrid cloud is any cloud infrastructure environment that combines both public and private cloud solutions.

The resources are typically orchestrated as an integrated infrastructure environment. Apps and data workloads can share the resources between public and private cloud deployment based on organizational business and technical policies around aspects like:

  • Security

  • Performance

  • Scalability

  • Cost

  • Efficiency

This is a common example of hybrid cloud: Organizations can use private cloud environments for their IT workloads and complement the infrastructure with public cloud resources to accommodate occasional spikes in network traffic.

As a result, access to additional computing capacity does not require the high CapEx of a private cloud environment but is delivered as a short-term IT service via a public cloud solution. The environment itself is seamlessly integrated to ensure optimum performance and scalability to changing business needs.

When you do pursue a hybrid cloud, you may have another decision to make: whether to be homogeneous or heterogenous with your cloud. That is—are you using cloud services from a single vendor or from several vendors?

Here’s who the hybrid cloud might suit best:

  • Organizations serving multiple verticals facing different IT security, regulatory, and performance requirements

  • Optimizing cloud investments without compromising on the value that public or private cloud technologies can deliver

  • Improving security on existing cloud solutions that must be delivered via secure private networks

  • Strategically approaching cloud investments to continuously switch and tradeoff between the best cloud service delivery model available in the market

Advantages of hybrid cloud

  • Policy-driven option. Flexible policy-driven deployment to distribute workloads across public and private infrastructure environments based on security, performance, and cost requirements.

  • Scale with security. Scalability of public cloud environments is achieved without exposing sensitive IT workloads to the inherent security risks.

  • Reliability. Distributing services across multiple data centers, some public, some private, results in maximum reliability.

  • Cost control. Improved security posture as sensitive IT workloads run on dedicated resources in private clouds while regular workloads are spread across inexpensive public cloud infrastructure to tradeoff for cost investments
