Do you have a chief cloud technologist? What about a cloud architecture engineer?
If you missed it on Federal News Radio the first time, take a minute to listen to Federal Tech Talk with host John Gilroy as he interviews DLT Solutions chief cloud technologist, David Blankenhorn. David fields questions on cloud architecture and discusses topics including:

When it comes to disaster recovery, there has historically been a limitation on disk storage. While tapes can easily be sent offsite to be used for restores after a site outage, disks do not offer the same flexibility.
Some OpenStorage technologies, support out-of-band replication in which the contents of the disk storage are replicated between devices. In these instances, NetBackup has no knowledge of the data, which complicates recovery in a NetBackup protected environment because the replicated data can only be accessed after recreating the NetBackup catalog. Replication is done by importing the entire contents of the disk storage at the remote site using the bpimport command. The nbcatsync utility, introduced in NetBackup 6.5.6 and 7.0.1, can address this challenge as well, but it relies on being able to restore the catalog from a catalog backup and then post-processing it to reconcile the disk device mappings, resulting in a very time consuming process.

The title of this series underscores our motivation for building a toolbox for system management, silencing the pager. In the first part of the series, we discussed the importance of standardization. We then talked about automation.  As we conclude the series, we turn our focus on resiliency. Operations management aims to keep failures to a [...]

LiveUpdate is a NetBackup feature that allows administrators to quickly and easily upgrade NetBackup clients under central control using a special NetBackup policy. Previous releases of NetBackup offered limited functionality for LiveUpdate, providing only the ability to upgrade to a minor update of the current version (e.g., from NetBackup 6.5.5 to 6.5.6). In contrast, NetBackup 7.1 has the ability to update a client even if it’s running a previous major version (NetBackup 6.5 and later). LiveUpdate operates with any supported NetBackup client system, including UNIX, Linux and Windows machines, and can update a mixture of UNIX, Linux and Windows clients from a single LiveUpdate policy.
It’s important to understand that NetBackup LiveUpdate is not the same as the LiveUpdate service that many other Symantec products use. The NetBackup version only runs when the administrator explicitly executes it and it does not pull data from Symantec or any other location on the Internet. All update information is contained on servers that are controlled by the NetBackup administrator. It’s also important to note that other installation methods are still supported; LiveUpdate is an optional tool. If administrators prefer to use the standard NetBackup client installation utilities, they may still do so.

The race to virtualize everything has created a host of unintended consequences, not the least of which is how to meet the SLAs (service level agreements) for application backup. As we move into cloud alternatives this problem will only grow since your cloud provider will have to provide this to you on an application by application basis.

Every virtual machine is essentially a set of large files such as VMDKs in a VMware context. These large files are typically stored in storage arrays which can be connected via iSCSI or Fiber Channel or on NFS volumes. Traditional data protection techniques such as VMware’s VADP, or VMware VCB rely on an agent to protect VMDK files associated with virtual servers.

Last time we talked about standard operating environments and how they can reduce stress and give back time. Now we’ll talk about managing not only systems but the SOEs themselves. Repeatable, reproducible, and remote are the watchwords for managing our environments.
Automation is no newcomer to the world of system management, but it remains a crucial component. While admins may find reasons to not standardize, they usually will find some way of automating repetitive efforts. A quote that has stuck with me is “a good sysadmin is a lazy sysadmin.” The premise here is if you have to do something manually more than once then you aren’t really doing your job. This includes backups, redundancy, and documentation, but it is automation that is key to all aspects of this particularly successful brand of laziness.
We will carry our library of scripts to each new environment from the last, layering in new methods and skills along the way like coral. While Jane’s scripts cover some scenarios and John’s may overlap, they go about things in a manner that can cause meaningful changes in functionality or user expectations. Even with a common scripting framework, personal changes in style can lead to divergence. TMTOWTDI (Tim Toady) is a great motto for a programming language but not for an efficient and tight knit system administration team.

One of the most effective ways to reduce fire fighting in daily administration is by standardizing the operating environments and automating deployment and configuration. A standard operating environment (SOE) that can support multiple use cases is a more robust and tested platform to build upon. It provides a uniform environment for troubleshooting when something goes awry. Reducing the differences in your operational environment to critical changes also reduces the overall complexity in multi-tier environments. Using centralized automation tools to define, build, and deploy these standards streamlines the process even more.

Standardization is not a new concept, nor is it disruptive way of thought. The industrial revolution owes part of its existence to standardization. Computers and gadgets get reviewed and reviled based on adhering to standardized parts and ports. Yet for some reason, every environment I’ve worked in has one-off, bespoke systems to one degree or another. Some had admins who thought it was easier, better, smarter, more secure to build custom environments. Some had admins who wrote wrapper scripts around standard UNIX utilities because they didn’t like the way a particular error was handled. The only real outcome was increasing difficulty of maintaining and replicating the systems. While bespoke suits will fit better at first, you’d best be prepared to work hard to exactly maintain your shape otherwise you’re in for regular and expensive tailoring.

One of the benefits of this job, and subsequently a benefit to readers of this blog, is my ability to interact directly with Oracle development. As a result, I can relay to my readers the latest and greatest updates on Oracle software and the current product direction of many of Oracle’s more popular product lines, [...]

Last week a diverse group of Industry executives were invited to meet with the President and his staff to offer their ideas on using technology to streamline government and make it more responsive to citizens. Memorable quotes reported from the meetings included…
