Issues with Public Cloud

Issues with Public Cloud


Public clouds are beyond your perimeter defense or edge firewalls and will require much more investment to secure and transfer existing management systems.

Management of Public cloud environments is a new industry and people are only now trying to solve this problem. (Cloud identity management.)

Application vendors might not support Public Clouds.

Many companies that jumped into the public cloud in 2012 have had bill shocks or struggled with internal compliance. They are now removing parts of their network away from public cloud to rationalise cost versus performance.

We’re finding many Australian government organisations are requiring people living and residing in Australia … a responsible attitude towards jobs.

Part of the reason why people try to rationalise to a single provider is to gain better control. They need to get on the path to rationalise all the [systems] to help them through that transformation.

Lock-in ; Public Clouds such as AWS or Azure require custom architectures and it is very difficult to move back workloads to traditional data centre solutions.

Data Sovereignty; It is difficult to take back your data from a Public Cloud vendor.

Public Cloud catastrophic Failures; There have been many catastrophic failures experienced in public clouds and usually these events effect all customers as the architecture is distributed and shared.

New Expensive Skills; Public cloud skills are a new and rare skills and not readily available compared to traditional datacentre skills like VMware or Microsoft.

Opex Expensive; Moving to a Public cloud Pay-as-you-go Model could be much more expensive when operated over a number of years..

Maturity – Any product or services will take several years to become enterprise grade. (example; Office 365 Exchange Online Protection is a very basic SPAM protection service. ) Traditional Datacentre technology is Enterprise Grade and has a mature ecosystem.

Some Workloads are not suitable Candidates for Public Clouds; Complex VLANs, Applications and High Performance workloads might not be suitable for Public Cloud offerings.

Compliance and Security (Customer managed) and Provider transparency; Customer will face great difficulty to secure public cloud environments and maintain Compliance certification. (PCI-DSS 30, APRA)

Secrecy; Public Cloud vendors are very secret and not transparent about issues or problems or even architecture.

Llack of interoperability standards, lack of data/system portability, and lack of migration choice/flexibility can be top concerns with the deployment of public clouds.

How do you backup, secure and compliance cloud servers and data.

Costs and Performance is difficult to identify
