Hi All

Before we start talking about NetScaler but there is one question comes in mind why NetScaler ? why not F5 or other devices. 

Why NetScaler:-

1. more than 10 million websites uses NetScaler at the moment and even Netscaler holds a strong position in cloud services.

2. biggest brand uses NetScaler in their environment like microsoft, Apple, mastercard, ebay and many more.

3. In cloud netscaler plays a major role in delivering web services and application.

4. Amazone AWS offer NetScaler instances to use with web applications.

Whats NetScaler:- In IT networking world  , Netscaler device can do almost everything,  work with IP routing technologies, works with OSPF, BGP and RIP technologies, perfect tool for load balancing services with the intelligence of backend server analysis, Acceleration by using Compression, TCP buffering, Traffic Shaping, SSL (encryption and decryption technologies) and unique product which support ICA Proxy stuff.

Type of Edition of NetScaler:- Platinum, Enterprise, and Standard

Each edition enables more features and speed for your environment but all the edition includes some features which are common.

a. Load balancing, SSL offload, High Availability and TCP optimization. 

the small list of features with the edition.

There are 2 kind of platform Netscaler provides.

1. Virtual - VPX appliance (can run on HyperV, Vmware ESXI XenServer & Linux KVM)

2. Physical - comes with MPX and SDX.

NetScaler VPX:- it cost less and easy to setup in HA or multiple instances but the only problem is the performance which depends on the H/W you are running it. any issue with underline Hypervisor layer will cause the problem for VPX performance.

NetScaler MPX:- its costly solution and comes with special H/W to support SSL traffic, limited to the single instance as it built in and would need another MPX model to configure the HA configuration. it offers better performance due to special H/W builts to handle Traffics. 

NetScaler SDX:- It a cost-effective solution for organization those needed multiple Netscaler instances. it runs XenServer OS which allows running multiple Ns instances.

so the decision is based on what you need to support your environment so pick wisely :)

Hi NetScaler Admin

Let's start learning Citrix NetScaler from Scratch and will cover the following netScaler Section under this.

After this Session would be able to handle the following Netscaler stuff.

1. Basic introduction to NetScaler ( http://www.ittechyminds.com/index.php?controller=post&action=view&id_post=25)

2. Architect solution any NetScaler environment

3.  NetScaler solution with High Availability

4. Load balance, monitor and improve reliability for any Application by using NetScaler

5. Optimize web application performance and how to avoid a large-scale outage 

6. Secure Web Applications

7. Secure XenApp Traffic

8. configure Citrix Access Gateways.

We will try to publish some self-made videos and written articles to share content for this Session.

Please follow the NetScaler Sections and try utilizing the content to boost your knowledge.

Thanks

Hi Cloud Admins

Here is very good article on the internet which explain the easy way to analyze your egress traffic and Google follow the same network charge mechanism to earn money :)

https://blog.doit-intl.com/the-truth-behind-google-cloud-egress-traffic-6e8f57b5c2f8

ingress traffic:-  Data originating outside the local network and process towards internal network . that is transmitted to a station within the network and google cloud dont charge for ingress traffic.

Egress Traffic:- Egress is apposite of it.  any traffic originating from LAN towards Regions, Internet or initiate from regions towards another region.

thanks

Hi Cloud Admin

Just one example from google training to how to save cost in computer 

its just simple example and depends more on your environment analysis

thanks

Hi Admin

Here is the list of commands can be used to generate the installed patches on windows Server.

Option 1

Get psinfo from http://technet.microsoft.com/en-us/sysinternals/bb897550.aspx

Run psinfo -h to get the list of hotfixes

Option 2

Another method that doesn't require 3rd party software using wmic; just type: wmic qfe from the command line. The default output gives really long lines, so you might be better off redirecting to a file and viewing it in your favourite text editor.

Variations on a theme include:

wmic qfe list full
wmic qfe get HotfixID,ServicePackInEffect,InstallDate,InstalledBy,InstalledOn
wmic qfe where "HotfixID = 'KBXXXXXX'"
wmic qfe where "HotfixID = 'KBXXXXXX'" get HotfixID, InstallDate, InstalledBy, InstalledOn
wmic qfe where "HotfixID = 'KBXXXXXX" list full
wmic /node:myserver qfe list full

Option 3
Use Powershell to do the same thing.

Local: get-wmiobject -class win32_quickfixengineering
Remote: get-wmiobject -class win32_quickfixengineering -computername mysever

Again, this can take filters, for example:

get-wmiobject -class win32_quickfixengineering -filter "HotfixID = 'KBXXXXXX'"
...or as it's Powershell, just pipe through where-object.

Option 4

You can try this instead:

$Session = New-Object -ComObject Microsoft.Update.Session
$Searcher = $Session.CreateUpdateSearcher()
$Searcher.Search("IsInstalled=1").Updates | ft -a Date,Title

Hi Admins

Please find the commands to unbind the Cipher from VServer.

Run the following command to create an user-defined group:

ADD SSL Cipher to Netscaler VServer

Add ssl cipher <cipherGroupName>

Run the following command to bind ciphers to a group:

bind ssl cipher <cipherGroupName> -cipherName <string>

Show the Cipher

Show SSL cipher Vserver <Vserver name>

How to bind the SSL cipher to Vserver

Bind SSL Cipher VServer <Vservername> -ciphername <Ciphername string>

Unbind the SSL Cipher for Vserver

unbind ssl cipher <cipherGroupName> -cipherName <string>

Thanks
