Povečanje zanesljivosti in zmogljivosti sistema za prodajo vstopnic

MERČUN, BOŠTJAN (author), Ciglarič, Mojca (mentor)

V času, ko spletne storitve uporabljamo na večini področij v življenju, je zelo pomembno, da so te storitve uporabnikom vedno dosegljive. Visoko razpoložljive storitve so nas, uporabnike, razvadile do te mere, da pričakujemo delovanje vseh storitev v vsakem trenutku, zaradi česar se je znižala tudi naša toleranca do njihovih nedosegljivosti. Vsak izpad delovanja lahko za podjetje pomeni izgubo strank in posledično dobička. V diplomskem delu bomo prikazali primer arhitekture za prodajo vstopnic preko spleta. Najprej bomo pogledali definicijo visoke razpoložljivosti, zakaj je pomembna in kako jo dosežemo. Nato bomo prikazali osnovne komponente, ki jih taka arhitektura potrebuje, definirali slabosti ter analizirali zanesljivost komponent. V nadaljevanju bomo ugotovljene slabosti odpravili in naredili arhitekturo visoko razpoložljivo ter s tem preprečili daljše izpade aplikacije in posledično izgubo strank. Visoko razpoložljivo arhitekturo bomo prilagodili še veliki količini sočasnih uporabnikov. Pri prodaji večjih dogodkov, ki se začnejo ob določeni uri, je uporabnikov ponavadi več, kot jih sistem zmore obvladati. Da nam zaradi obremenitve aplikacija ne bi odpovedala, bomo arhitekturi dodali čakalno vrsto, ki bo poskrbela, da bodo strežniki stregli le toliko uporabnikom, kot jih zmorejo obvladati. Na koncu bomo ovrednotili končno arhitekturo in pogledali, kako smo testirali in izmerili izboljšave.

• Title: Improving reliability and performance of a ticket shop system

Abstract

At a time when Internet services are being used in most areas of life, it is very important that these services are always available. Users have become accustomed to highly available services to such an extent that they expect internet services to be available at any time, resulting in no tolerance of downtime. Each downtime can mean loss of customers and therefore of profit. In this thesis we will show an example of an architecture needed for selling tickets online. First we will look at the definition of high availability and explain why it is important and how we can achieve it. Then we will show the basic components of such architecture, define their drawbacks and analyze the reliability of individual components which we will later improve in order to prevent longer downtimes and consequently loss of customers. Highly available architecture will be further improved to handle high number of parallel users. When events are sold at a certain time, more users can visit the site than the system can handle. In order to avoid crashing the system, we will add a waiting room to the architecture which will ensure that web servers only get as many users as they are able to serve. At the end, we will evaluate the final architecture and evaluate how we tested and measured the improvements.
