Popular Workload on Public Cloud

Posted by admin in Market Update on September 24, 2010 with No Comments

IDC (the research firm) has conducted a survey early this year on what would be the most popular workload that people going to use the cloud for.

The bottom 3 are the Agnostic ones, where people don’t really worried (or don’t care) if it’s not within their premise/control, hence the most suitable to be in the ‘public cloud’.

Workload remain the critical point when deciding on public vs private cloud deployment. Choice of deployment model is a business alignment issue.

Web Security in the Cloud: More Secure! Compliant! Afforable!

Posted by admin in Market Update on September 11, 2010 with No Comments

Interesting report published by the Aberdeen Group. Basically it compares the web security infra between the on-premise in typical enterprises vs. the infra on the cloud — the cloud infra seems to have a more complete and updated security infra.

Check out the report yourself per below

——-

This Aberdeen Group report addresses how the cloud can render web applications more secure, more compliant and less expensive. It reveals how users of cloud-based web security have achieved substantially better results than users of on-premise web security. In short it shows the numerous benefits of security in the cloud for your organisation! Read the full report to find out more.

We are Tailored for Web Infrastructure Hosting

Posted by admin in FAQ on September 1, 2010 with No Comments

How do we compare?

Our cloud servers are tailored for web infrastructure hosting, unlike some of our competitor (i.e. Amazon EC2), which is a less targeted virtualization solution.

Feature Description SKALI Cloud Competitor
Basic virtualization Run multiple virtual servers on physical hardware.
Free choice of operating systems Easily run any operating system designed for PC hardware and any software on your virtual server.

(pre-installed options or self-install from any standard install CD)


(difficult to create custom AMIs; no FreeBSD)
Fully flexible sizing Resize your server, changing your processor, memory, disk or bandwidth on demand to fit your current capacity needs.


(only 8 fixed instance sizes)
Automatic redundancy and failover Rely on automatic reboot of your virtual server in the unlikely event that it terminates due to software or hardware failure, together with persistent storage of all your data, without the need to explicitly store on EBS or S3.

Why we chose KVM virtualisation

Posted by admin in FAQ on September 1, 2010 with No Comments

Answering to some of the queries from our beta testers on why we chose Linux KVM as our virtualisation hypervisor.

Before selecting Linux KVM as our de-facto hypervisor, we have evaluated other popular hypervisors in the market (VMware, Xen – very similar to KVM, while Virtuozzo is only at OS-level containers). We have selected KVM as the best architecture for virtualisation on modern processors with fast hardware virtualisation support (VT-x and NPT on Intel or AMD-V and EPT on AMD).

Historically, virtualisation platform used software to trap and simulate certain instructions, memory management and I/O in the host virtual machines. (VMware was an early leader in this software technology)

With the 1st generation of hardware virtualisation, the VT-x/AMD-V extensions trapped these instructions in hardware, giving a significant speed improvement. However, virtualised memory management and I/O remained bottlenecks. Xen was an early proponent of paravirtualisation, which attacks those bottlenecks by modifying the host operating system at compile time.

With the 2nd generation of hardware virtualisation, the NPT/EPT extensions minimise the memory management bottleneck. As a result, MMU paravirtualisation is a legacy approach, leaving just scheduling and I/O to be virtualised in software by a hypervisor. (I/O virtualisation requires a good set of device drivers for the underlaying hardware, of course: an area in which Linux excels.)

Linux KVM is a hypervisor which is built into the mainline Linux. It uses the full range of hardware virtualisation support, and directly uses the regular Linux scheduler and I/O device drivers. KVM technology has rapidly emerged as the next-generation virtualization technology, following on from the highly successful Xen implementation.

We believe the KVM architecture is superior to both Xen and VMware, since the mainline Linux scheduler and device drivers are both extremely well designed, widely deployed, professionally maintained and thoroughly tested, to a level likely well above what a single company can achieve on either their own proprietary codebase or locally maintained fork of Linux.

Even Red Hat has announced a strong support for KVM hypervisor in it’s virtualisation strategy moving forward (ditching Xen).

So what does that means to you as our client or potential clients?

Besides confidently having a proven and stable platform that runs our cloud service, the KVM itself is an open virtualisation technology that are community driven, thus it definitely able to drive our infrastructure cost down, that in turns, we are able to pass that saving to you by providing our service at a very competitive rates.

We focus on maintaining the server infra for you, while you focus on developing your application and systems on it to serve your customers.
