What is Vertical scaling and Horizontal scaling – Vertical and Horizontal hardware / services scaling

If you're coming from a small or middle-sized company to a corporations like HP or IBM probably you will not a clear defined idea on the 2 types (2 dimensions) of system Scaling (Horizontal and Vertical scaling). I know from my pesronal experience that in small companies – all needed is to guarantee a model for as less probels as possible without too much of defining things and with much less planning. Other thing is being a sysadmin in middle-sized companies, often doesn't give you opportunity to discuss issues to solve with other admins but you have to deal as "one man (machine) for all" and thus often to solve office server and services tasks you do some custom solution.
hence for novice system administrators probably it will be probably unclear what is the difference between Horizontal and Vertical Scaling?

Vertical Scaling (scale vertically or scale up) :- adding more resources(CPU/RAM/DISK) to your server (database or application server is still remains one).
Vertical Scaling is much more used in small and middle-sized companies and in applications and products of middle-range. Very common example for Virtual Scaling nowdays is to buy an expensive hardware and use it as a Virtual Machine hypervisor (VMWare ESX). Where a database is involved using Vertical Scaling without use of multiple virtual machines might be not the best solution, as even though hardware might suffice (creation of database locks might impose problems). Reasons to scale vertically include increasing IOPS (Input / Ouput Operations), increasing CPU/RAM capacity, and increasing disk capacity.
Because Vertical Scaling usually means upgrade of server hardware – whenever an improved performance is targeted, even though if Virtualization is used, the risk for downtimes with it is much higher than whenever horizontal scaling.

Horizontal Scaling (scale horizontally or scale out):- adding more processing units (phyiscal machine) to your server (infrastructure be it application web/server or database).
Horizontal scaling, means increasing  the number of nodes in the cluster, reduces the responsibilities of each member node by spreading the keyspace wider and providing additional end-points for client connections. The capacity of each individual node does not change, but its load is decreased (because load is distributed between separate server nodes). Reasons to scale horizontally include increasing I/O concurrency, reducing the load on existing nodes, and increasing disk capacity.
Horizontal Scaling has been historically much more used for high level of computing and for application and services. The Internet and particular web services gave a boom of Horizontal Scaling use, most companies nowadays that provide well known web services like Google (Gmail, Youtube), Yahoo, Facebook, Ebay, Amazon etc. are using heavily horizontal scaling. Horizontal Scaling is a must use technology – whenever a high availability of (server) services are required.

The Treasures of Hermitage, Saint Peterburg Russia and its imitation Hermitage in Amsterdam

Sankt-Peterburg-Hermitage

Since some time, I'm very interested in Russia culture as it is so inter-related to our culture in Bulgaria. .It is sad that nowadays Bulgaria is not with Russia, we share much more cultural and heritage roots with Russia than any Western European county or even generally Europe. Thus I believe for every Bulgarian and generally for anyone interested in art, maybe the most remarkable place to visit if you're in Russia is the city of Saint Peterburg. There is found the Russian National State museum. The Hermitage is a museum which historically used to be Winster Palace (Residency) for the Russian Tsar / King. What is unique about this museum is it is one of the oldest and largest museums in the world. The musem was founded in 1764 and since 1852 is in open for public visits. The museum consists of 3 000 000 unique items. Only a small number of those 3 million are exposed for public visitors. The museum contains artifacts from all around the world including very rare things like Mummy sarcophagus. The amount of gold in mostly everywhere is remarkable the ornaments and everything is amazing. For people who value art it is a must see. I still did not have the opportunity to see it with my own eyes. But even seeing it on a video is very  worthy.

As I'm currently in Holland, it was very interesting to find out one of the worthy things to see in Holland is an imitation of st. Peterburg's Hermitage in Amsterdam. There is plenty of beautiful and unique works in it too, as you can check in below video.

Rojdestvo Hristovo romanska ikona - Romanian Holy mosaic of the Nativity of the Lord Jesus Christ
I Wish Happy Christmas, to my dear readers. I wish to anyone who reads around. The Lord Jesus Christ to give good faith, peace, joy, health and heavenly blessings.

While checking various Church troparions on Nativity of Christ (including some Troparions) of the Russian Church I come across a short story, retelling the glorious events occuring around the birth of the Saviour of the world Jesus Christ! I'm currently having as a guest a girl from Belarus which and Belarusians speak Russian as their mother language. Thus I have the opportunity to learn a lot of Russian. In that relation finding such a video re-telling the story of Messiah (Christ's) birth was great opportunity to both improve my Russian language comprehension and enrich and strengthen my faith. The video is enjoyful so I hope it might help others in situation similar to mine. Enjoy!

Did you that every single day there are …

Saturday, April 7th, 2012

Do you know that every single day there are:

  • 150 Million Blogs being read
  • 60 Million New Facebook Status Updates
  • 140 Million New "Treets" …
  • 2 Million New Videos Posted to Youtube per day
  • 3.3 Billion! Product and Information Searches
  • 188 Billion! Emails Sent …

 

This statistics were sent to me just few weeks, ago by a friend. I have no clue where he got the statistics, but the numbers are really amazing. From a business perspective point of view this numbers are tremendously HIGH! Nowadays only about 2.5 billion people are actively using the internet daily.

This means more than half of the humanity is still about to join using the internet in the 10 or 15 years to come. Though the continuous use of internet has a very bad impact on us. It is a tremendously big business opportunity field. With this said definitely business innovative people and enterpreneurs should reconsider, there strategic plans for potential products and extend or include the internet in anything they do in order to maximize profits.

All this is just news for anyone who is involved somehow actively with the net (like me), so system admins, web designers, programmers, use your brains and start making money from the internet. If one doesn't start with monetarizing his high tech skills, its quite likely some bad tied suit guy took the lead and made his millions or billions  on our back 🙂

The week

After 10 minutes I’ll have Deutcsh lessons anyways I’ve caught some winter virus :)I’m having snots coughing and stuff. In Sunday I was on a Liturgy in the Church as usual.Yesterday was a quiet and peaceful day. Static came home and we installed Windows. NowI have Windows,Linux,FreeBSD on one machine. I’m surprised how well is Windows working.I’m eating a lot of garlic recently to stimulate my immune system. Yesterday I playedsome Warcraft III. Having Windows now gives me the opportunity to play some gameswhich weren’t working in wine. Well that’s most of how my day passed. I went to seemy grandma and she made me tea as always (her tea is awesome!). :)END—–
