Instructions

Reading digital theses in the closed network of the Aalto University Harald Herlin Learning Centre

In the closed network of Learning Centre you can read digital and digitized theses not available in the open network.

The Learning Centre contact details and opening hours: https://learningcentre.aalto.fi/en/harald-herlin-learning-centre/

You can read theses on the Learning Centre customer computers, which are available on all floors.

Logging on to the customer computers

  • Aalto University staff members log on to the customer computer using the Aalto username and password.
  • Other customers log on using a shared username and password.

Opening a thesis

  • On the desktop of the customer computers, you will find an icon titled:

    Aalto Thesis Database

  • Click on the icon to search for and open the thesis you are looking for from Aaltodoc database. You can find the thesis file by clicking the link on the OEV or OEVS field.

Reading the thesis

  • You can either print the thesis or read it on the customer computer screen.
  • You cannot save the thesis file on a flash drive or email it.
  • You cannot copy text or images from the file.
  • You cannot edit the file.

Printing the thesis

  • You can print the thesis for your personal study or research use.
  • Aalto University students and staff members may print black-and-white prints on the PrintingPoint devices when using the computer with personal Aalto username and password. Color printing is possible using the printer u90203-psc3, which is located near the customer service. Color printing is subject to a charge to Aalto University students and staff members.
  • Other customers can use the printer u90203-psc3. All printing is subject to a charge to non-University members.

Abstract (eng): Over the past few years, cloud computing and cloud storage systems have rapidly gained popularity.
The field is still immature, but it has evolved fast to a point where these NOSQL databases are becoming a serious alternative to relational databases in increasingly diverse situations.
Cloud storage systems are already widely used in large installations handling massive volumes of data.

The telecom industry and service providers have been slow to move to the cloud.
The benefits of the move have not been significant enough to justify the risks involved.
As technologies have evolved and cloud storage systems have matured, however, the original misgivings and risks have diminished.

This thesis will examine whether cloud storage systems are suitable for telecom services.
Three of the most popular candidates are first compared and then the attention will be concentrated to Cassandra, which will be examined in detail from a telecom service perspective.
Shortcomings in scalability, data API and load balancing will be addressed in this work.
Results show that despite being still somewhat immature, Cassandra is a suitable storage system for a variety of large-scale telecom services.
Abstract (fin): Viime vuosina pilvilaskenta ja pilvitallennusjärjestelmät ovat kasvattaneet suosiotaan voimakkaasti.
Ala on vielä nuori, mutta nopean kehityksen ansiosta niin kutsutut NOSQL-tietokannat ovat jo varteenotettava vaihtoehto relaatiotietokannalle.
Tällaisia tallennusjärjestelmiä on jo tuotantokäytössä isoissa järjestelmissä, joissa jo pelkkä datan määrä on pakottanut kehityksen uusille alueille.

Telealan yritykset ovat siirtyneet hitaasti pilvilaskentaan.
Siirtymisen edut eivät ole olleet tarpeeksi merkittäviä riskeihin verrattuna.
Teknologioiden kehityksen ja varteenotettavien tallennusjärjestelmien synnyn myötä alkuperäiset epäilyt ja syyt varovaisuuteen ovat kuitenkin käymässä vähäisemmiksi.

Tässä työssä luodaan katsaus NOSQL-järjestelmien nykytilaan ja tutkitaan kolmea suosittua järjestelmää.
Tämän jälkeen keskitytään Cassandraan ja tutkitaan sitä yksityiskohtaisesti telemaailman näkökannalta.
Havaitut ongelmakohdat skaalautuvuudessa, rajapinnassa ja kuormituksen tasapainottamisessa tuodaan esiin ja korjataan.
Tulokset osoittavat, että vaikka Cassandra ei ole vielä kaikilta osin optimaalinen pilvitallennusjärjestelmä, soveltuu se jo nykyisellään käytettäväksi telealan järjestelmissä.
