Abstract:Web hosting has a lot of problems, such as
low security, waste of bandwidth resource or sudden
lack of resource. A self-adaptive cloud computing
architecture——RA-Cloud architecture (Resourceaware Cloud Computing Architecture) based on web
security in resource-aware situation is proposed. This
architecture uses cloud computing technology and selfadaptive linear regression model to estimate the
dynamic migration threshold and to search the most
suitable neighbor node for data migration. This platform
and algorithm distributes the huge amount of computing
resource to many server “end” according to the resource
constrained self-adaptive policy. The new method
increases the user access speed, enhances the anti-attack
ability, blocks the attacks effectively and improves the
web site security.
