#Gartner analyst slams #OpenStack, again – #IaaS
Good article and I must agree that OpenStack has quite a long way to go before the “average” enterprise embraces it…
OpenStack still has maturing to do before it’s really ready for the enterprise, analyst says
Network World – Gartner analyst Allessandro Perilli recently attended his first summit for the open source cloud platform OpenStack and he says the project has a long way to go before it’s truly an enterprise-grade platform.
In a blog post reviewing his experience, the analyst – who focuses on studying cloud management tools – says that OpenStack is struggling to increase its enterprise adoption. Despite marketing efforts by vendors and favorable press, enterprise adoption remains in the very earliest stages, he says.
Don’t believe the hype generated by press and vendor marketing: OpenStack penetration in the large enterprise market is minimal.— Gartner analyst Alessandro Perilli
Sure there are examples like PayPal, eBay and Yahoo using OpenStack. But these are not the meat and potatoes types of enterprise customers that vendors are looking to serve. Why? He outlines four reasons, most of which are related to the process and community nature of the project, and less around the technical maturity of it. By the way, this is not the first time a Gartner analyst has thrown cold water on the project.

Lack of clarity about what OpenStack does
There is market confusion about exactly what OpenStack is, he says. It is an open source platform that can be assembled together to build a cloud. It, by itself, is not a cloud though just by downloading and installing it. OpenStack requires some heavy lifting to turn the code into an executable cloud platform, which is why dozens of companies have come out with distributions or productized versions of OpenStack code. But, the code itself is not a competitor to cloud platforms offered by vendors like VMware, BMC, CA or others. Read more…
#Citrix #AppController 2.5 Implementation Tips – #CloudGateway, #BYOD
Great blog post by Matthew Brooks!
AppController is a component of the Citrix CloudGateway Enterprise suite that orchestrates access to Enterprise Cloud applications. Those applications may take many forms including Mobile Applications, Software-as-a-Service hosted in public clouds, and Web links. Below I provided some tips to help with the implementation of AppController 2.5 (which is the latest version as of the publishing of this blog).
System Related
Including settings such as the Hostname, SSL certificates, and Restore.
TIPs:
- Take a hypervisor level snapshot after the initial installation so that you can easily return to that base level if configuration or integrations efforts go awry.
- The hostname cannot contain special characters in the AppController certificate signing request.
- The hostname must match SSL certificate.
- The system cert must be chained to its CA/(s).
Active Directory Related
Including settings such as the Server (Domain Controller), Base DN, and Service Account credentials.
TIPs:
- The AppController only supports integration with a single domain. Multiple domains require multiple AppControllers. The NetScaler Access Gateway may be configured to allow users to access a single fully qualified domain name, yet be directed to their respective domain AppController through the use of Global Groups. See CTX116169 for more informationhttp://support.citrix.com/article/CTX116169
- All user accounts must have a first name, last name, and email address configured or they will receive an authorization error when attempting to launch applications. The bind Administrator account must also have email address configured or directory integration will fail.
- Only LDAP (TCP 389) may be configured through the wizard that must be completed initially. Thereafter LDAPS (TCP 636) may be configured through the full administration menu.
- If the server name domain name is a load balanced DNS entry the initial import may work, yet subsequent bind attempts will fail. Alternatively you may use the IP address of an LDAPS load balancer on a Netscaler with specific domain controllers configured as services. See CTX135092 for more information http://support.citrix.com/article/CTX135092
Network Related
Including settings such as the IP address, @Workweb and NTP server.
TIPs:
- Use IP private addresses as system addresses if possible. When Trust Settings are configured for NetScaler Access Gateway it does not allow SSO to public addresses. If public addresses must be used the NetScaler may be configured with an SSL Bridge to access the AppController. See NetScaler Traffic Management document for more information.
- NTP must be configured or SAML authentication may fail for SaaS sites if the time difference is significant.
- When Trust Settings are configured for NetScaler Access…
