The cloud is the future of networking. Today there are more options than ever before for companies to take advantage of the benefits of the cloud to transition resources from traditional on-prem data centers. These options can include public, private, or hybrid cloud environments, but with all of these options comes complexity. Trying to plan for the future, while still utilizing some traditional security and monitoring tools that live in the data center is causing challenges, primarily around security and packet visibility in the cloud.
Let’s go over the basics.
A private cloud solution resides on the company’s intranet or hosted data center, where data is protected behind a corporate firewall. Private cloud can be a great option for companies with large data centers, so they can make use of current infrastructure, with enhanced security and control over resources. Private clouds can be costly to manage and maintain over time, since the responsibility falls completely with the organization, which may not have the talent and resources to effectively manage the cloud.
Private Cloud Visibility
With organizations becoming more dependent on virtual computing, there also needs to be a solution to eliminate the blind spots inherent to virtual environments. Virtual TAPs are a software solution that addresses these challenges by providing complete visibility for east-west and inter-VM traffic.
Private Cloud Advantages
Public cloud is an appealing solution, and the most common method of deploying cloud computing for many companies, as the public cloud provider owns the cloud resources and delivers them to the customer over the Internet. The cloud provider is responsible for the daily management and maintenance of the data center resources, which keeps the cost for the company down. Individual company data is kept separate from other companies in public cloud environments, however some believe that public cloud is a less secure solution.
Public Cloud Visibility
With critical information in the public cloud, organizations also need visibility into the traffic in the cloud to acquire and distribute cloud traffic to other cloud-based tools. A lack of visibility can make it difficult to secure information in the cloud. Prisms is the easiest and most advanced solution to get public cloud packet traffic to monitoring tools and services. Prisms allows organizations to access, process, and deliver packet-level traffic from VMs and containers in any public cloud.

Common uses of Public Cloud
A hybrid cloud solution uses the combination of on-prem infrastructure and public or private cloud resources to reap the advantages of both solutions. Organizations can make use of the different resources for different operational and technology needs in an integrated manner that ensures optimal performance and can meet changing business needs.
With resources moving to the cloud, securing the cloud becomes just as important for an organization as securing on-prem resources. Cloud security comprises all of the resources, mechanisms, and strategies that are used to protect applications and data stored in, or processed by the cloud. It handles the same responsibilities that would be the focus in a traditional data center environment; securing applications, protecting data, authentication, and supporting compliance, but you have the ability to perform these activities in a flexible manner.
Cloud security can bring about many benefits for an organization. With resources living in the cloud, rather than in an on-prem or collocation data center, you eliminate the risk of onsite breaches, misplaced devices, personnel risks, and natural disasters causing havoc to the security of your network. Cloud environments have strict regulatory standards, guaranteed confidentiality, and DDoS mitigation.
However, migration to the cloud is still a new concept for many companies, and companies need to make sure that the provider they choose to use has an advanced security solution that is at least comparable, if not better, than what exists in the data center. The cloud is not infallible. It’s at risk to cyber threats and breaches, and must be protected both by the provider and implementation and best practices from the user.
