KT ucloud storage provides an OpenStack Swift-based object storage service. Some key points:
- OpenStack Swift allows for redundant, scalable storage across standardized servers capable of storing petabytes of data. It ensures data replication and integrity.
- KT customized Swift for their use, adding middleware for SSL performance, integrating their single sign-on system, and enabling real-time usage reporting.
- To commercialize Swift, KT deployed it based on commodity servers and disks across 5 zones with 3 replications for redundancy, using automated deployment with Chef.
- While Swift is stable, deploying it on hardware can introduce problems. KT also found it difficult to increase revenue as object storage is a new concept for

Сервис последней мили: почему сейчас это особенно важноTOCHKA
Сервис последней мили: почему сейчас это особенно важно
• Объемы продаж (соответственно доставок) – падают. Грустно, но факт.
• Повышение тарифов – неизбежно, так как под влиянием внешних факторов рост операционных затрат происходит постоянно. Совсем не весело, но то же факт.
• Платить бОльшую сумму за те же услуги потребителю сложно, и часто проще отказаться от них, чем «принять».
• Выход - наполнять «последнюю милю» дополнительным сервисом. Давать потребителю возможность получать вместе с доставкой/выдачей комплексную услугу.
• Что это даст? Наполнение «смыслом» растущие цены, увеличение % выкупа, рост лояльности и удовлетворенности - и это только на первый взгляд!
Как, что, зачем и почему – в цифрах, графиках и с веселыми картинками – только на IForum 2015!

OpenStack and Containers have rapidly emerged as the default technologies for developing and delivering new scale out architectures. Initially, these workloads were deployed in test and development environments. But now that they're reaching the production phase, it's time to rethink and update your approach to data protection. Attend this session to examine the best models, mindsets, and approaches for providing complete, effective data protection for today's new scale-out workloads.
The lessons I learned is that Open source quickly becomes the natural choice wherever commoditization is happening in the software stack. Thus we expect business-to-business open source, which is already a significant trend in recent history, to become an increasingly common form of open source collaboration. Companies who understand the ground rules of business-to-business open source will be better positioned to identify and take advantage of open source opportunities in the competitive spaces that they share with other companies.
So I will share why open strategy is import for the enterprise. And how to do contributions for the open source projects n today’s topic.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex Pruden
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

10. Who am I ?
Why am I here ?
Let’s Start, Swift!
12. OpenStack Object Storage (a.k.a Swift) - Capabilities
• Redundant, scalable object storage using clusters
of standardized servers capable of storing petabytes of data
• Distributed storage system for static data. Having no
central "brain" provides greater scalability, redundancy and
durability.
• Reliability: Objects and files are written to multiple disk
drives spread throughout servers in the data center, with
the OpenStack software responsible for ensuring data
replication and integrity across the cluster.
• Scalability: Storage clusters scale horizontally simply by
adding new servers. Because OpenStack uses software logic
to ensure data replication and distribution across different
devices, inexpensive commodity hard drives and servers
can be used in lieu of more expensive equipment.

31. What I am trying to say is...
• Upload, Download, Big Size, Small Size, Many files
in a container, Many containers, etc.
• There can be lots of use cases.
• Gather your usage data and Analyze patterns,
then focus on what you need to improve the
most.
33. • OpenStack Swift is a very stable and
mature software stack.
• However, prepare for the various
problems, when it deployed on Hardware
34. • In terms of business,
• People Does Not Know “Object Storage”
35. • It has been
• NOT “selling a service”
• BUT “explaining what it is and how to use”
• and frankly speaking,
• KT has been experiencing difficulties to
increase revenue from object storage service.
36. • Educate the customer and Find Business Model
with them.
• This is a new concept for the customer.You
should put “object storage” concept at their
initial service design
• Grow your potential customer pool with active
support
• AWS S3 took 3 years. Be patient.
• Various promotion for younger developers &
students
