“Le Cloud computing est un modèle permettant un accès réseau
permanent et à la demande à un ensemble partagé de ressources
informatiques configurables (ex : réseaux, serveurs, stockage,
applications et services). Il offre une grande flexibilité, un effort de
gestion minimal et peu d’interaction avec le fournisseur de service.”

“If we built our own infrastructure for high-capacity storage and asset management, we would
have had big capital costs to install and maintain the servers and other equipment, as well as
high rent for a Manhattan location to house it. If you consider all those factors, it was
advantageous to choose a cloud-based service that not only hosts our media content but
makes it accessible to our production and sales staff around the world. Instead of shipping
physical media, like hard drives or thumb drives, or doing FTP and UDP file transfers, which
can be a cumbersome, time-consuming process, we upload our content and it’s immediately available for screening or download by authorized parties around the world.”

“Media professionals need to do a cost/benefits
analysis of owning, leasing, or renting. If they can
get three to four years out of their capital
equipment, they’ll typically do better making
the CapEx investment in terms of total cost of
ownership. But if the market is changing, and they
need to upgrade every two years, they’ll typically do better paying as they go [OpEx].”

“In the past, we relied on FTP transfers or used cloud-only file transfer services but found they were not easy for all clients to work with and large file transfers were very slow. Today, 90% of incoming files, and 100% of outgoing files, are sent via a hybrid cloud-based product from Signiant called Media Shuttle that efficiently accelerates and manages file transfers and sharing of hundreds of gigabytes of high-value content.”

“As a software editor, we would like ultimately to use the GPU solution in the cloud to deport
the 3D rendering of our applications to a server farm. The remote desktop technology has
become possible thanks to the bandwidth increase of large companies, in addition to the
increase of the computing power of the specialized clusters (e.g. HPC). The advantage of
such an architecture for our customers is to save graphics resources, by allowing
them access a large computing capacity thanks to (theoretically) a screen and a network
card.
La majorité des services réduisent la qualité du flux d’images pour permettre d’avoir une
vidéo plus ou moins fluide avec un délai acceptable […], mais cette tendance changera
probablement avec l’expansion de la fibre optique et l’optimisation de la technologie qui
n’est actuellement qu’au stade embryonnaire.

Qualité de Service dans le Cloud
“One of the most interesting aspects about the 2012 Ericsson Mobility Report is that video has
become the biggest contributor to data traffic volumes (25-40 percent) and is growing faster than
ever. Mobile devices are now a crucial component in the TV experience, which has caused an
explosion in mobile data traffic and rapidly increased demands on the networks. The report also
shows that the subscription types associated with large data volumes (such as those for mobile
PCs and smartphones) are expected to exceed 4 billion by 2018, while mobile data traffic for
smartphones will grow up to 14 times between 2012 and 2018. With the global consumer shift
towards broadband mobility continuing to grow, I think we will see an even greater number of
operators demanding a more all-inclusive approach, one that encompasses the entire content
delivery and distribution system. As we move into an ever more mobile age, where multi-screen is
increasingly ubiquitous in every operator’s TV offering, the need for an efficient and flexible
unified CDN will become ever more pressing.”

“Fast access to archival video clips can give a news story
historical context and added value. But there’s a capital
cost to digitizing, storing, and managing years of
legacy footage, especially to buy, house, and maintain a
robust storage infrastructure.”

Qualité de Service dans le Cloud
“The greatest single point of failure is typically the Internet connection at the live event
site. As long as users can push the stream up to us, we’ll do whatever we need to do to
ensure their live events stream as planned. For mission-critical live events, we recommend
that customers have a redundant internet connection to ensure the stream is successful. The
cloud can provide immense flexibility for publishing to browsers, tablets, social media, and
mobile outlets. When customers want to stream live video, they send a single encoded
stream of that event to Haivision where it’s packaged into multiple bitrates and codecs
needed for multiple devices and published via a video content management system. It’s far
better video quality than they could get by trying to send multiple high bitrate streams from
their on-site Internet connection.”

Qualité de Service dans le Cloud
“One of the biggest issues impeding
creative teams and agencies is the high
volume of digital assets and big data
starting to clog up the networks, which
is frustrating when they need to share
large, rich-media assets globally in a
timely and reliable manner. To address
this, we've integrated Aspera into
SocialBridge so teams can get campaigns
up and running faster than the competition
without the bottlenecks that come with
other systems available today.”
Arnulf Hsu, CTO and co-founder of Central Desktop Arnulf Hsu, CTO and co-founder of Central Desktop
“The work that Central Desktop is doing to
proliferate cloud collaboration is cutting-
edge, and we're very excited about this
integration to help move its clients' data
at maximum speed.”

Service de streaming live dans le Cloud
“For live streaming, there are many advantages to leveraging a cloud transcoding
environment that is also live, not file-based. Users that have limited connectivity, budget
constraints and a need to reach all Internet connected devices should consider live
transcoding as an option. Using Haivision live transcoding, content creators can offer
viewers a high bitrate stream [of their camera or switcher output] via a single Internet
connection - then we package it into multiple ABR, Dynamic Flash, and Adaptive HLS
codecs. Customers are seeking to monetize the value of their streaming content, but typically
not through advertising. Live streaming of events can save on travel and other operating
costs, promote more efficient learning and communications, allow organizations to work more
efficiently, and offer live broadcast quality video where they otherwise couldn’t.”

Risques liés à la sécurité dans le Cloud
“For our customers, security is the number
one concern because they don’t want to
lose control of their client’s valuable media
assets or the content they’re developing for
their own distribution. Avid customers shy away
from public cloud services because they don’t
feel the security concerns have been
adequately addressed.”

Risques liés à la sécurité dans le Cloud
“There are two chief concerns for high-end post houses: security risks and technology
limitations. When movie studios, cable networks and other major production companies
entrust them with their high-value assets, post houses don’t want to lose control of this
content, and they feel the public cloud is still too risky. They even take the precaution of
not putting Internet connectivity on their local storage networks. Since the RAW assets are
terabytes of HD, 2K, or 4K resolution data processed at up to 200 Mbps, you can’t work on a
cloud due to Internet bandwidth limitations. Yes, you can work with proxies, but we’re
years and years away from moving these demanding applications off-site, especially
to the public cloud.”

“If a customer wants to build a massively scalable encoding platform, with future-proof
support for the latest devices and players, ad insertion, closed captioning, and analytics,
among other features, it would be cost-prohibitive to build what we’re able to offer our
customers. The amount of effort it takes to maintain and upgrade a video transcoding
and streaming platform and to make sure it’s compatible with the latest devices is not
trivial. But the nice thing about a cloud provider is upgrades happen almost invisibly
to the user. When Zencoder [owned by Brightcove] makes a change, say it’s a 10-20%
improvement in video compression for HLS, users realize those gains for free, without having
to do anything to make it happen. They can just focus on creating great content.”
