"Computing at the Edge" is a 30-page white paper that discusses the
trends associated with edge computing as well as platforms, management,
security and specific examples of customers using Sun technology to
implement effective edge computing strategies.
Edge computing has emerged as an important strategy for providing
scalable and highly available Web Services for organizations
worldwide. Data center build-out at the Edge is bringing about new
ways for deploying and managing servers and services. Beyond simply
finding better ways to manage growth and bandwidth, the Edge is
enabling new applications that promise to change some of the
fundamental ways people make use of the Internet.
Edge computing deployments will take many forms and will move the Web
into new uses and roles. In particular, Sun sees the emergence of
distinct types of edge environments that serve the network, customer
and data center.
Edge technology begins with software, for applications are now defining
deployment. With IP networking assumed throughout the industry,
application development is now focused at a platform-independent
layer. The open source movement has brought a wealth of popular and
portable applications, resulting in portable and modular Web Services.
Beyond platform independence, the modular nature of these modern
development environments allows applications to be fundamentally
disaggregated or de-layered and distributed. Since the JavaTM Virtual
Machine (JVMTM) fundamentally abstracts the service or application
from the underlying server and operating environment, application
components can run where it makes the most sense for the application.
(The terms "Java virtual machine" and "JVM" mean a virtual machine for
the JavaTM platform.)
Today's data centers must provide both scalability and availability to
the application services they support. The multi-tiered
service-delivery architecture has evolved as a result. By layering
functions into multiple tiers, organizations can optimize scalability,
availability, manageability and security by using techniques
appropriate for each tier.
Wireless devices use new protocols and require translations and
trans-coding of existing Web content. The nature of content is
changing as well and contributing to Edge build-out. Beyond simple
caching of static information, organizations are increasingly
delivering customized and dynamic content to their customers. As Web
Services are deployed, edge servers enable new devices and services
while enhancing the performance of systems in tiers 1-3 by off-loading
the processing of key protocols and specialized functions.
Customers need a range of choices for edge computing servers in
addition to effective management and security solutions. Edge
computing will likely remain a heterogeneous environment with server
platforms selected for their capabilities or the ability to run
applications the best. Powerful but compact Linux and UNIXR servers have
proven themselves in edge environments by coupling strong performance
with popular applications, security and remote administration
Sun provides an end-to-end product family, including both Linux and
UNIX system edge servers, along with management products and
comprehensive security to help organizations deploy edge computing
strategies effectively for better scalability, availability and
