CIOs Debate Cloud Strategy

Cloud SecurityEnterprise computing systems have traditionally comprised servers, storage, and networking devices that came from different companies. Many times those products have depended on other technology for performance and have been discounted in package deals. A similar model is emerging from the cloud as CIOs debate the best systems for structuring multiple vendors in their cloud strategy.

Single vs Multi-vendor Cloud Platforms

CIOs are trying decide if they should move toward single or multi-vendor cloud platforms. One idea is to split computing workloads between vendors, since using multiple platforms is costly and takes up resources. The problem with this model is that it means slowing down work, such as training people twice.

Many times it’s more efficient to work with one vendor. CIOs are looking for a single cloud platform that’s more affordable and offers sensible scalability and security without a vendor lock-in agreement — a package that is hard to find. While CIOs are seeking to avoid lock-ins, they will likely have to deal with them since that’s the direction the cloud is moving. At the moment many CIOs are deciding between platforms such as AWS and Microsoft Azure.

Another one of the major challenges that CIOs are facing in determining a cloud strategy is deciding between leaving data centers behind or approaching the growing market for sharing workloads between data centers and the public cloud.

Cloud Flexibility

Moving from one cloud provider to another is usually not a big issue unless custom services are initiated, which creates dependencies within the original cloud structure. If an app is dependent on the vendor’s domain name and connection with a relational database, it can pose a challenge for moving to a new provider. Otherwise, moving an app from one provider to another is simple.

Dependence on specialized cloud services is tied to how much one uses them. CIOs must decide between standardizing an app for cost and efficiency and creating a more outside the box solution that yields better performance.

Businesses might benefit by starting with a few different cloud partners to gauge quality and scalability. It’s best to test a cloud solution before agreeing to a long-term commitment. Ultimately, creating the right application architecture is the key to CIOs meeting their goals in the cloud.

Conclusion

CIOs need to establish appropriate policies and frameworks to oversee an effective cloud strategy. In recent years they have experimented with huge cloud platforms such as AWS and Azure to test scalability and cloud efficiency. CIOs must weigh the costs and productivity involved with using single or multiple vendor platforms.

Why SDN Needs to Emphasize Network Security More

Network SecurityThe next generation of networking includes software defined networking (SDN), as network controls shift from hardware to software. It’s the result of merging multiple devices into one controller, which empowers the user to control an entire network. It’s a giant leap in the evolution of administrative control, but developers must still face network security challenges for this new technology.

Control Plane Concerns

The main concern that users should have about SDN at this stage is that the control plane can be compromised. A separate issue involves the scalability of the control plane. If a hacker is able to gain access to the control plane, they can potentially control the entire network. Another part of the risk involves how easy it is to misconfigure architecture due to the flexible nature of the software.

SDN as a Networking Solution

Despite the network security issues, SDN is quickly becoming a solution for overcoming modern networking problems. One of the reasons for this trend is that it allows for maintenance dry-out. It also answers several other technical issues. The network is set up to respond to its own threats. The problem is that new product developers are not spending enough time working out security issues.

More Than a Buzz Word

SDN is still not clearly defined, which adds to the uncertainty surrounding network security. Many people have used SDN as a buzz word, as different companies such as Cisco have their own definition of it. Various vendors are defining it based on how it fits their existing product lines. Even though SDN is supposed to make a network more consistent, its ambiguity creates confusion.

SDN is not really a new development, but it has the feel of new technology since all the bugs have yet to be worked out. Developers also need to work on making the technology more stable. What’s more, there aren’t many SDN specialists yet, as networking or data center teams have been left in charge of it.

Industry leaders warn that teams using SDN must be careful about hardware rules concerning switches. They also point to multiple layers of security as the safest solution, whether the business uses SDN or not. One of the major benefits of SDN technology is that it allows for fast reconfiguration.

Conclusion

Businesses that have quickly adopted SDN to resolve networking solutions need to consider that this technology still has network security issues. SDN will become more efficient once more focus is put into making the solution more secure. It is becoming widely used due to the simplicity of consolidating all controls into one controller.
