Evgeny Tugarev worked as a project associate at CERN from 2004 to 2009. He contributed to several major projects, including developing a tool to synchronize and restore websites hosted on Microsoft IIS and migrating mailing lists and applications to SharePoint. Evgeny demonstrated strong technical skills, the ability to adapt quickly to new tasks, and worked well both independently and as part of a team. His work was completed in a dedicated, reliable, and systematic manner. The letter serves as a recommendation for Evgeny and highlights his qualifications and accomplishments during his time at CERN.

A FAULT-TOLERANCE LINGUISTIC STRUCTURE FOR DISTRIBUTED APPLICATIONSVincenzo De Florio
The structures for the expression of fault-tolerance provisions into the application
software are the central topic of this dissertation.
Structuring techniques provide means to control complexity, the latter being a relevant factor
for the introduction of design faults. This fact and the ever increasing complexity of today’s dis-
tributed software justify the need for simple, coherent, and effective structures for the expression
of fault-tolerance in the application software. A first contribution of this dissertation is the defi-
nition of a base of structural attributes with which application-level fault-tolerance structures can
be qualitatively assessed and compared with each other and with respect to the above mentioned
need. This result is then used to provide an elaborated survey of the state-of-the-art of software
fault-tolerance structures.
The key contribution of this work is a novel structuring technique for the expression of the
fault-tolerance design concerns in the application layer of those distributed software systems
that are characterised by soft real-time requirements and with a number of processing nodes
known at compile-time. The main thesis of this dissertation is that this new structuring tech-
nique is capable of exhibiting satisfactory values of the structural attributes in the domain of soft
real-time, distributed and parallel applications. Following this novel approach, beside the con-
ventional programming language addressing the functional design concerns, a special-purpose
linguistic structure (the so-called “recovery language”) is available to address error recovery and
reconfiguration. This recovery language comes into play as soon as an error is detected by an
underlying error detection layer, or when some erroneous condition is signalled by the applica-
tion processes. Error recovery and reconfiguration are specified as a set of guarded actions, i.e.,
actions that require a pre-condition to be fulfilled in order to be executed. Recovery actions deal
with coarse-grained entities of the application and pre-conditions query the current state of those
entities.
An important added value of this so-called “recovery language approach” is that the exe-
cutable code is structured so that the portion addressing fault-tolerance is distinct and separated
from the rest of the code. This allows for division of complexity into distinct blocks that can be
tackled independently of each other.

Re: Letter of recommendation for Mr. Evgeny Tugarev
Geneva, November 12, 2013
To whom it may concern,
Evgeny Tugarev has been working as an project associate in the Desktop Services section of the Internet Services Group
of CERN’s IT department. He stayed in our group from October 15th
, 2004 until March 31st
, 2009. Evgeny was working
in the CERN Web Services team whose role it is to provide a consistent Web hosting infrastructure for the laboratory and
its collaborators. Presently the CERN Web-services operate a range of about 50 Web servers that host about 12000 Web
sites.
Evgeny’s very good technical knowledge and his capability to quickly adapt to new tasks allowed him to contribute
valuably to numerous tangible results during his stay at CERN. The major projects Evgeny was working on were a the
design and implementation of a synchronization tool to save and restore Websites hosted on our Microsoft Internet
Information Services (IIS) infrastructure. The tool recorded the server configuration “meta-base” and the security state of
each site and allowed to perform Internet Information Services disaster recovery. Evgeny was the principle developer of
this successful project. Another large project that Evgeny was working on was the “E-space project” that aimed at
providing a better collaboration environment for the large CERN community based on SharePoint services. The tasks
achieved by Evgeny comprised the complete migration cycle of existing Microsoft Exchange based mailing lists to
SharePoint discussion boards, the implementation of custom SharePoint website provisioning handlers (for more than
1000 sites in 2009), and the important CERN-market application where a smooth migration of the old NNTP buy/sale
board to a SharePont web application was achived. In addition, throughout his stay at CERN, Evgeny participated to all
operational aspects of the CERN Web services and provided highly reliable 3rd
level expert support for CERN users. The
technical environment used for the various developments done by Evgeny comprise .NET, C, C#, SharePoint / MOSS,
and scripting laguages such as PowerShell and VBScript. During all his stay Evgeny also prepared very comprehensive
documentation of his work.
Evgeny is working very well in a team and is also very good in solving tasks autonomously. In all the activities
mentioned above Evgeny has demonstrated his very wide range of knowledge as a computer scientist that allowed him
to quickly adapt to any task assigned to him which he solved in a very dedicated, reliable and systematic way.
Yours sincerely
