When it comes to measuring applications’ performance across our local enterprise network, we think we know what network latency is and how to calculate it. But when it comes to the cloud there are a lot of subtleties that can impact latency in ways that we don’t immediately realize.
In his session at the 10th International Cloud Expo, Jelle Frank van der Zwet, Manager of Cloud Segment at Interxion, will more closely examine what latency means for deploying cloud applications, how you can keep track of it and reduce it for your particular purposes and cloud-based applications.
Lack of bandwidth is a problem in many developing countries, including the Philippines, as I’ve written before. Now comes word that about 100 gigabytes-per-second capacity has been added to the Philippines, with completion of the country’s portion of a cable that will reach many countries in Southeast Asia.
The country’s dominant telco, Philippines Long Distance Telephone (PLDT), has invested US$50 million in the project, which is known as the Asia Submarine-cable Express (ASE). The ASE is expected to come into full service in Q3 of this year. Original cost estimates for the entire project were US$300 million – PLDT describes it as a US$500-million project in its latest official information.

The industry has long worried that cloud computing cannot deliver the performance required for critical enterprise applications. For example, the very notion of multiple compute instances or multiple applications sharing the same infrastructure has meant that service providers cannot guarantee service level agreements for response times. This has held many companies back from making the jump to the cloud. These performance bottlenecks are indicated in Figure 1. Multiple applications or virtual machines simply drive too much storage traffic to traditional disks, which cannot keep up with demands.
Rackspace, which wants to be the “Linux of the cloud” mimicking the now billion-dollar-a-year Red Hat, said Monday that it’s “drawing a line in the sand against cloud providers.”
Everyone agrees it has Amazon, particularly, and VMware, to a certain extent, in mind. However, what’ll probably end up happening is that Red Hat, which has a prominent part in the open source OpenStack project that Rackspace started, becomes the “Linux of the cloud” because it’s got all the pieces, or thinks it does, but that’s another story.
Anyway, Rackspace is inching out with a production-ready OpenStack cloud based on Essex, the fifth and best-yet release of the open source cloud platform put in train by Rackspace and NASA in the summer of 2010.

There are fundamental differences between data centers and the Internet of Things, which means that fundamental Cloud architecture principles must also transform to support this new reality. This transformation promises to be truly disruptive — a true paradigm shift as we figure out what it means to implement what we call Cloud-Oriented Architecture.
Quick quiz for all your Cloud aficionados out there: what’s missing from the NIST definition of Cloud Computing? To make this challenge easy for you, here’s the definition: “Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.” Give up? What’s missing is any mention of data centers. Sure, today’s Clouds typically consist of resources in data centers, running one way or another on racks full of physical servers. But there’s nothing in the definition of Cloud that specifies anything about the physical location of Cloud resources.
Cloud computing is all the rage.
«It’s become the phrase du jour,» said Gartner senior analyst Ben Pring. The problem, according to InfoWorld, is that everyone seems to have a different definition of cloud computing.
Some analysts and vendors define cloud computing as an updated version of utility computing: virtual servers available over the Internet. Others go broad, arguing anything you consume outside the firewall is «in the cloud,» including conventional outsourcing, according to InfoWorld.
InfoWorld talked to dozens of vendors, analysts and IT customers on various components of cloud computing. Here is InfoWorld’s rough breakdown of what cloud computing is all about.
