Today's blog post is on Frugality, yes it's all about FREE sneak peek into eBooks (mostly IT).

Getting access of ebooks excerpt is really easy, there are some popular e-commerce site which give free downloadable access to first and second chapters like www.amazon.in, www.packtpub.com, and www.safaribooksonline.com.

1)Amazon.in- It's the most famous book site and they provide 'Look Inside' feature to get a sneak peek into your favorite titles (mine favorite is IT). Amazon also gives access to downloadable previews using their free kindle ebook reader software available for major mobile and PC platforms.

2)Packt Pub- Another major book selling site plus publisher. This site facilitate the download of free chapters in pdf format

3) Safari books online- Not much popular in my perspective, but it gives you almost full access to 'rough cuts' of 'coming soon' titles (isn't it awesome), what you need to do is, get a demo account for 1 $ only or can get a free trial & access rough cuts.

Sharing progress on Python Learning & Tweaking vSphere Shortcut

Learning Python course from http://www.codecademy.com/, 58% completed till date. Hopes are high on this one. I think if i practice Python regularly, i will soon advance to intermediate level. great job to me.

Another progress i'm making on learning Hadoop (it's kind a side project), completed the "CBT Nuggets for Hadoop" course and built my single node hadoop install for revision and testing hadoop commands. however installing hadoop for single node is pretty straight forward (if you got the right guide), don't worry i will document the steps for the same in future blog post.

one cool trick that i want to share with you guys is how to automate login into vSphere Client with tweaking vsphere client shortcut.

For logging in with your Windows session credentials:

-s vcenter.yourdomain.com -passthroughAuth

For logging in with any other credentials:

-s vcenter.yourdomain.com-u username -p password 

So, if you're like me and manage 5-6 vCenter servers, this will really help you out.

TGIF...

Thinking out loud-vCenter server on Hyper-V

Today i was thinking about a scenario, where i was thinking to put vSphere infra components (Like vCenter server, syslog, AD, DNS, DHCP etc.)above Hyper-V Cluster.

i know what you're thinking, what absurd thing i'm talking about, what is the need of separate management cluster, Hyper-V is not mature enough to host vSphere Management infra., VMWare and Hyper-V don't go Hand-in-Hand etc. and i accept that, because before conceiving this concept i had same thoughts but later i cross questioned myself i.e. what is pros/cons about this design and how this is going to help the customers. So, i'm sharing the pros/cons about this design with you, if you any comments whether good or bad, i'm all ears.

Pros or advantages:-
1)Dual Hypervisor strategy with a twist.
2)Most of the vSphere infra components require windows OS (yeah,i know about VCSA).
3)Utilize "Virtualization-Safe" feature introduced in win2012 (VM-GenerationID, avail. with Hyper-V v3), make SSO robust.
4)License cost reduced (at least for management cluster and OS license).
5)Utilize existing hardware and windows OS license.
6)vCenter server supported on virtual platform (kb10087), nothing mentioned about Hyper-V

Cons or disadvantages:-
1)Requires multi-talented engineers to manage.
2)Support-issues from both vendors (support engineer love this sport, Volley-ball).
3)Some Third-party software issues (i don't know which, but included it).
4)Hard to convince CIO/CTO's (biggest threat to such designs)

If you have something in your mind about the above conceptual design, please share your thoughts.

thanks
