Difference between Scale Up vs Scale Out

Scale Up: Get a Bigger Box

With this approach, you add hardware such as processors, RAM, and network interface cards to your existing servers to support increased capacity. This is a simple option and one that can be cost effective. It does not introduce additional maintenance and support costs. However, any single points of failure remain, which is a risk. Beyond a certain threshold, adding more hardware to the existing servers may not produce the desired results. For an application to scale up effectively, the underlying framework, runtime, and computer architecture must scale up as well. When scaling up, consider which resources the application is bound by. If it is memory-bound or network-bound, adding CPU resources will not help.

Scale Out: Get More Boxes

To scale out, you add more servers and use load balancing and clustering solutions. In addition to handling additional load, the scale-out scenario also protects against hardware failures. If one server fails, there are additional servers in the cluster that can take over the load. For example, you might host multiple Web servers in a Web farm that hosts presentation and business layers, or you might physically partition your application's business logic and use a separately load-balanced middle tier along with a load-balanced front tier hosting the presentation layer. If your application is I/O-constrained and you must support an extremely large database, you might partition your database across multiple database servers. In general, the ability of an application to scale out depends more on its architecture than on underlying infrastructure.

Office 2013 Installation Error : Code 1603

Wanted to share one error that I got while installing Microsoft Office Professional 2013 for which I had to spend almost 3 days to find the root cause. I also googled and found that many people have also faced the same issue but did not get if anyone had the solution. Sharing the solution that worked for me. Thanks to Dhaval Metrani, my colleague, who also helped me with this. If you get the following error in the log file (in the %temp% folder) while installing Office 2013 Failed to install product OSMMUI.msi ErrorCode: 1603  and the detail log shows ERROR: The network address is invalid then the same is because of Task Scheduler service is not enabled on the machine. 1603 is a generic error and some people have mentioned that the same could be related to deleting/renaming  %programdata% /Microsoft Help but the solution seemed to be related to Task Scheduler when the exact error was related to 'Network address invalid'. By default in Windows 7 and Windows Vista ...

jQuery Intellisense support in Eclipse 3.4.2

To have jQuery Intellisense feature in Eclipse, I tried to find out the way in Google and everyone suggested to use modified version of Eclipse WTP. After doing some research I found out another way of having jQuery Intellisense in Eclipse i.e. integrating Spket IDE with Eclipse. I am using Eclipse 3.4.2 Ganymede version. Download Download and Install Spket IDE and jQuery Download Spket plugin for Eclipse using Eclipse Update Manager, from Spket update site - http://www.spket.com/update/ Once the Spket IDE is installed then download jQuery from http://jquery.com/ and save in your local disk. Configure The steps to configure jQuery Intellisense are: Open Eclipse IDE Select the menu item Window > Preferences... to open the workbench preferences. Select the Spket > JavaScript Profile preference page to display the installed JavaScript Profiles. Click the New.. button. In the Name field, type jQuery (you can type anything) as the name for the new profile. Then click OK . Click th...

India's Economy pre and post Covid-19(Corona) pandemic

Before Corona (Covid-19) Pandemic By Feb 2020, India had seen six successive quarters of declining GDP growth equalling the longest slowdown in the past 23 years. The GDP growth in second quarter of FY19-20 fiscal shrunk to 4.5% from 5% in the previous quarter. This was the sixth straight drop in India's quarterly GDP growth.  The slowdown was expected to be the third slowdown since 1996 and will be the longest in the past 23 years if the Q3 GDP falls below 4.5%. Note: From January 2015, the Central Statistics Office (CSO) updated base year for GDP calculation to 2011-12, replacing the old series base year of 2004-05. After Corona and 5+ weeks of lockdown During the Corona crisis and 5+ weeks of lockdown in response to contain it, we have already seen significant impact to Indian economy in various forms. Sensex and Nifty indices have crashed nearly 30-35% and BSE 500 stocks have crashed nearly 50% (before Corona, it had already crashed 50%) and m...
