Is Public cloud ready for enterprise application such as Office Applications?

Posted on September 29th, 2011 in Data Center, Tips | No Comments »

Microsoft had pushed very hard for the office 365 to all their existing client doesn’t matter they are SMB or Enterprise. Personal opinion, I had tried out the office 365, the experience is useable but it doesn’t meet the requirement of my expectation for office use. Anway, this is just 1 of the down side. When you look at the infrastructure readiness and dependancy, I think enterprise may putting too much risk as now to adopt to office 365.

If the office 365 are able to be dedicated connectivity and resources with robust infrastructure behind, it could make a lot of different for many users to be considered.

Recently there are many outage happen on the cloud provider, which alert many of the users start to re-think to the strategy of cloud to minimize the business impact in the event of unexpected outage. A right strategy for Cloud can bring benefits to the company, but a wrong strategy of cloud could end up create disaster to the environment too. Those major outage top news had forced the service provider to further enhance the infrastructure uptime.

This report explain the uptime been claimed by Google and Microsoft both.

Cisco and VMware Submitted VXLAN for Open standard

Posted on September 2nd, 2011 in Announcement, Data Center, vCloud, Virtualization | No Comments »

Interesting announcement from Cisco and VMware during the VMworld 2011 which was regarding the VXLAN capability. Both company had invited a group of product principle together to submit the VXLAN to IETF for approval as a standard for future.

Let’s talk a little bit more about what is VXLAN and why do we need that. As of today, DR solution are commonly deploy by every enterprise environment. Did you realize 1 of the biggest challenge which always happen on the DNS record, hard coded IP segment, subnet and VLAN which always require human interaction to manually change it, to allow a success fail over of the DR scenario? Well, I think this is just 1 of the major issue commonly face. With Cisco Nexus 7000 come with OTV (Overlay Transport Virtualization) which allow you to stretch the Layer 2 traffic over Layer 3, with minimal bandwidth requirement. Cisco had done a great job to the enterprise to address this, which now you can have both side learning the same VLAN, Subnet and ip address. A DNS and ip changes is no longer require as both end are transparent with similar VLAN.

VMworld 2011 had focused a lot on private and hybrid cloud computing environment which address the concerns from enterprise over the public cloud offering in the market today. One of the key highlight during the event was the new capability over vCloud director version 1.5.

With vCD 1.5, you can now manage both private and public as a hybrid mode from the administration with secure federated. It allow you to subscribe, manage, relocate and provision anywhere you prefer, could be internal infrastructure or public cloud provider you choosen and manage in same console. I went through the hands on lab session for this topic and found the setup was great.

NFS advantage over SAN in cloud computing

Posted on September 2nd, 2011 in ESXi, Hardware, Industry News | 1 Comment »

Went through a session of sharing this morning from the federal goverment about the development and testing as a servic cloud computing in real deployment for experience sharing. The session was interesting with details architecture sharing how it was deployed by the presenter.

One of the key area they highlighted was the stoage protocol they choosed, which is NFS rather than iscsi and FC SAN, which was mainly due to the flexibility of volume shrink or resize that could support on the fly. I am agreed with their statement as personal thought, for large scale deployment, NFS are much easier to manage compare to Iscsi and FC environment.
