IBM 攜手Pivotal 雲端開放平台技術

IBM與Pivotal兩家科技大廠24日宣布，要在Pivotal的雲端開放平台技術Cloud Foundry進行合作，聯手迎戰亞馬遜公司建立的雲端運算平台馬遜網路服務（AWS）。
華爾街日報報導，IBM與Pivotal結盟凸顯隨著企業愈來愈依賴雲端技術，同時減少依賴公司內部電腦中心之際，亞馬遜、微軟、Google與IBM等科技大廠的競爭加劇。
Pivotal是資料儲存設備大廠EMC與旗下銷售雲端架構軟體的子公司VMware分拆出來的軟體公司，它的Cloud Foundry技術能讓企業撰寫可在雲端運作、與其他使用者分享的軟體應用程式。
Pivotal執行長馬利茲（Paul Maritz）表示，他希望Cloud Foundry能成為雲端的「作業系統」，如同微軟的Windows作業系統稱霸個人電腦市場。
目前最大的雲端勢力是亞馬遜的AWS，可讓網路電視業者Netflix等公司「租用」運算資源。其他業者則擔心亞馬遜及Google等其他崛起的雲端運算業者正改變許多公司運作的方式，導致現有的雲端業者邊緣化。他們正急著建立有別於AWS與Google雲端平台的企業雲端產品，這場戰役攸關未來網路、手機以及數位服務的運作方式。
Cloud Foundry、雲端大廠Salesforce.com旗下的雲端平台Heroku，以及紅帽公司推出的OpenShift平台，正極力爭取贏得開發商為各自的平台開發雲端應用程式與商用技術。

Cisco Data Center Application Network Solution ANS

A lack of ANS lead to

Fragmenting of device
inflexibility and poor util
Proliferation of Network Appliances
Increased TCO

Advantages

Virtual Logical Appliance e.g. FWSM, IDSM, ACE
Module vs Appliance (250 logical device, RBAC)

ACE GSS site select based on content – Content Routing Site Selection
ACE GSS 4492R Global Load Balancer, Proximity refer to distance in topology not distance, lowest round trip time
ACE XML Gateway – SOA Strategy, XSL Transform, Schema Validation, XML Encrypt/decrypt, XML Digital Sign, DMZ, Protect from app threat

Server Load Balance SLB – in turn – session maintain

ACE can handle - IP Fragmentation attack, Unauthorized access, IP Spoofing

Cisco WAAS
WAE (Wide Area Application Engine) or WAVE (Wide Area Virtualization ENgine)

Cloud – News Center

Cloud Management Broker means to integrate multi cloud service provider’s resource into one simple management tool

or portal. For example, CloudStack and OpenStack‘s management platform are belong to Cloud Management Broker business

model because their platform combine VMware, Xen, and KVM hypervisors, and its’ private cloud and Amazon public

cloud resource. This type of service is relate to our Newegg service portal(Peter and I are work on and discuss now). When

we development Newegg service portal, we can refer these metrics to define more advance futures to increase our value.

Linux – Tips and Tricks

You will need to reinstall rpm as it looks like rpm is damaged.

The rpm package only comes in .rpm format so will need to use the rpm2cpio command to install. rpm2cpio can be copied from another machine

if you dont have it.
mkdir -p /var/tmp/xxx
cd /var/tmp/xxx
rpm2cpio rpm-4.0.3-1.03.6x.*.rpm | cpio -dim
find . -type d -exec chmod 755 {} ;
tar cf - ./usr ./etc | (cd /; tar xvf -)

Then do "rpm --rebuilddb" to fix your database.
