Cloud Computing Discussion: Shel Waggener (UC-Berkeley) Presenting
Shel briefly described work he and Brad Wheeler (Indiana University)
have done in cloud computing, specifically that cloud computing is
based on two principles:
1. Scale - Can cloud computing effectively service an entire higher
ed. institution? a collection of higher ed. institutions? Scale
matters to fundamentally disrupt the current paradigm and ability to
be as cost-effective as possible.
2. Flexibility and elasticity/dynamic allocation - How adaptable is
the environment? Where can we burst/shrink consumption?
Aggregation of demand is necessary when talking about scale to this
degree. The proposed solution is not yet clearly defined, and as
architects we need to acknowledge and embrace the level of risk in
cloud computing so uses of cloud services are managed effectively and
to the best advantage to higher ed. institutions. From an
architectural perspective, we need to think about how we are solving
our campus problems and how they can be better solved jointly and
• In-house management costs on average $2/GB per month (fully loaded)
to manage storage/scale for an individual enterprise.
• Cloud providers can get fully loaded costs of storage down to under $.30 GB.
• Server layer: average admin can get upwards of 120-140 servers per admin.
• Scale of cloud computing: 1000+ servers per admin.
• Economics shift from capital expenditure model to operating expenditure model.
• Policy and regulatory issues can be roadblocks to adoption, but are
inexorable and will be addressed.
• Underlying policies need to be addressed: e.g. who owns the data?
Who has access to the data? Who backs up the data? Where are backups
Open Discussion/Points Discussed:
o Many institutions are currently building private clouds; this is an
opportunity to extend private clouds into public cloud architecture in
a managed fashion rather than the chaos of different units outsourcing
on their own, which can result in higher cost long-term. We need to
re-think how private clouds should be integrated into public clouds,
to consider policies and regulations involved, and share resources
o At the low end of the risk scale: architecture design that are
supported by CIO and endorsed by campus leadership, includes policies
to require some level of utilization, gives a pattern of design
against which common architecture can be benchmarked and extended. In
parallel, we need to experiment and share results of experimentation
regarding how we model utilization of services.
o At the high end of the risk scale: signing large contracts for large
capacity with a given provider locks us in individually to a given
situation where we still need to acquire services from other cloud
providers, but would still need to interface with all cloud providers
without control over the API layer. Cost of collaboration slows us
down, but without the scale to bring to cloud providers, we are
producing a higher-risk model.
o A consortium of institutions, like Internet2, would be well
positioned to bring enough scale to cloud providers. Institutions are
negotiating with cloud providers individually, which is a higher-cost
model to education. A large enough consortium is needed to manage the
chaos of different cloud providers to allow for sustainability and
scale. Current model means vendor-lock-in: you are able to get your
data, but cannot access meta-data; VM environments are proprietary.
o "Uniqueness" is not important at all layers: for example, branding,
UI presentation, data management need to be unique; infrastructure
does not need to be. There is no differentiation/value-add to the end
user community to being unique at the infrastructure layer.
o Standardizing certain layers of the stack is necessary to be able to
leverage them in terms of scale and flexibility.
o High-level & Long-term goals (next steps):
• Overall cloud computing strategy needs to be developed.
• IT models are currently push models; we need to shift to a pull model of IT.
• If we don't develop a strategy/model, every unit at an institution
will be instituting cloud computing in disparate manners. The
challenge will be to understand where we need a level of coordination,
and where it's OK to let go of control.
Shel will send additional resources to Jim, for sharing with the group.
