The Truth about Multi-Cloud

Next Generation App

Get ready for this one… not all multi-cloud offers are created equally. Here are a few ways ‘multi-cloud’ is being used to describe what’s happening with (and in) the multiple clouds.

Multi-cloud – multiple clouds, each hosting a different application belonging to the same organization

In this case, the commonality between clouds is most likely the person managing the cloud. This person is probably jumping from one user interface to another – Microsoft, AWS, Joyent for example. He or she is probably going through the hassle of learning (and keeping him or herself up to date!) with all the user interfaces as well as the terminology and the tool chain of all the clouds involved. Instead, this person could do with a consistent interface between all these clouds, to help simplify the management process and speed up the deployment and the day-to-day operation of his applications across multiple clouds.

Chef Made Easy

Next Generation App

Chef are industry leaders in IT automation, offering significant benefits such reducing the time and effort, as well as risk of manual error, involved in building, configuring and managing application stacks. For the DevOps community, this is great.

Chef’s a fantastic tool that most people want to dig into straight away. First, though, you have to set it up and configure the Chef servers and clients including all the various dependencies involved. Then you have to manage, pull and execute Chef cookbooks. This is in many cases a repetitive task. The good news is you can manage Chef more easily by having Flexiant Concerto carry out these tasks for you. Here is how.

Network Scalability: Layer 2 Issues

Cloud Network Scalability

To overcome cloud networking scalability challenges as outlined in a previous blog post, cloud service providers look to solutions like Layer 2, VLANs and Layer 3. Discussed below are the issues service providers face with Layer 2.

Layer 2 issues

One of the first challenges in scaling the cloud provider’s network comes at layer 2.

To explain this, it is first necessary to recap how a switched Ethernet network works. Each network interface card (physical or virtual) participating in a layer 2 network has a unique MAC address. Each packet contains a header (the MAC header) containing the source and destination MAC address of the sending and receiving network interface. The switches on the layer 2 network learn the source addresses of any packet passing through them. When a switch comes to forward a packet to a given destination, it looks up that destination in the forwarding table that it has learnt, and if an entry is present, the packet is forwarded to that port. If an entry is not present (or if the packet is a broadcast packet), the packet is forwarded to all ports. Such forwarding to all ports is to be avoided as they use bandwidth on each port as well as switch capacity. It is thus vital the forwarding table can contain entries for all source MAC addresses in use.
