CloudStackのネットワークを理解しよう
CloudStack を少しでも触ったことがある人であれば、ネットワークに関する知識がかなり必要であることに気づくでしょう。こちらのビデオシリーズでは、CloudStackのネットワークについて、Product Architect, Chiradeep Vittal が解説しています。まだ私も全て見ていませんが、非常に興味深いです。----- Episode 1 :Intro to Network Services with CloudStack 概要: CloudStackが提供できるネットワークサービスの概要を話しています。この後のEpisodeで紹介する各ネットワークサービスについて、キーワードを取り上げています。----- Episode 2: Network with CloudStack- Security Groups 概要: セキュリティーグループについて解説しています。セキュリティーグループとはAmazon EC2で使われているものと同じで、L3レイヤでのアイソレーションの技術です。ハイパーバイザーレベルで実装されるFirewallのようなものですね。例えば、Web層とDB層で構成されるシステムの場合、DB VMにはシビアなルールを適用し、Web VMとしかコミュニケーションを認めないように設定し、Web VMには、インターネットから接続できるようなルールを適用するなどが考えられます。ただ、この機能は、ハイパーバイザーに依存するものなので、ハイパーバイザーに多数のルールが適用される場合などは注意してください。また、セキュリティーグループの機能は、ハイパーバイザーによって違いますので注意してください。XenServer + Service Pack はベストです。（※ちなみに、このService Packは、まだ公開していませんので、もう少し待っていただければと思います。） KVMでも使えます。VMWは今調査中のようです。----- Episode 3: Networking with CloudStack - VPN----- Episode 4: Networking with CloudStack: Redundant Router----- Episode 5: Networking with CloudStack- Firewall セキュリティーの観点から、CloudStackが提供しているネットワークサービスを考えてみましょう- Security Groups: すでに説明した通り- Firewall: スタンダードなFWの機能を提供しています。- NAT- ポート転送: スタンダードなポート転送また、物理FW (Juniper SRX) をCloudStackと使用することも可能です。今後は、Vyatta仮想アプライアンスをCloudStack環境で使用することも簡単になるでしょう。また、CiscoやJuniperなども考えているようです。今後が楽しみです。----- Episode 6: Networking with CloudStack- Load Balancing----- Episode ...
Automated XenApp CloudFormation
Using Powershell & Amazon CloudFormation I first started building proof of concepts in the Amazon cloud over two years ago. You can read about all of them here. We've come a long way with the recent developments we have been working on with Amazon. Since then, Amazon has released some new tools that make a datacenter in the cloud very apetizing. Recent tools now allow ...
Pizza and Clouds – Reloaded
In a recent post I argued that enterprise IT's distrust of service provider Infrastructure as a Service (IaaS) is often based on lack of understanding. In particular the unfamiliar nature of the API-centric, services-based architecture of IaaS, by comparison with the concrete feeds+speeds of today's physical IT world, leaves many IT Pros cold. Of late I've found myself using an analogy of buying Pizza ...
VMware Project Redwood = Dead Wood?
It's widely acknowledged that the combined ingenuity of the Amazon Web Service team and the creative and fast-moving Xen community led to the creation of the first Infrastructure as a Service (IaaS) Cloud - Amazon EC2 - as far back as 2006. So it has been interesting to see VMware attempt to co-opt the concept and turn a profound capability that ...
Security Groups in Amazon EC2
For XenApp farms in EC2In a previous post, I talked about how to build a XenApp Farm in Amazon EC2. I was reminded through a comment on the post, that a XenApp Farm usually is deployed with certain degrees of security separation between the servers. Having left that out of the Deployment Guide, I decided to create an additional deployment guide that shows ...

Cloud Computing – Private and Public
One hundred and fifty billion dollars! That's $150,000,000,000 or €107,635,000,000 or ¥14,458,000,000,000. In any currency we are talking about a lot of money. According to some estimates this represents the total projected revenues for Cloud Computing by 2013. Don't you wish you could capture just a small percentage of that total market? Just think, a 2% capture rate would yield $3,000,000,000 or €2,152,700,000 or ¥289,160,000,000... still a ...
Cloud Burst
Cloud Networking is secure and robust You can create a complete end-to-end network from one cloud network, running on XenServer, through a VPN to another network in a different cloud. All servers and hosts communicate securely over SSL VPN. Amazon Machine Images are secured by the Amazon infrastructure using security groups.The proof of concept speaks for itself. Between the Softlayer cloud ...
How to get your own Citrix XenApp server in EC2 for 12 cents & 15 min.
OK, actually it's 12.5 cents and it might take you a few minutes longer, but compared to the traditional methods of building/configuring servers the cost and time savings is dramatic. It is now possible to launch a pre-built XenApp image in the Amazon Web Service offering called EC2. The image includes XenApp 5.0 on Windows 2003 Server ready to run and is accessible as an ...
