The document discusses the significant growth of cloud computing research in Brazil, noting over 480 papers presented at various conferences between 2013 and 2017. It addresses challenges in migrating applications to the cloud, including issues with portability, costs, and resource management. Finally, it proposes the establishment of a Special Interest Group (SIG) to address the diverse needs related to cloud computing in multiple domains.

2. Cloud in Brazil
● Let’s see some informations about cloud in Brazil
– Number of publications on cloud
– Number of conferences
– Principals conferences

3. Cloud in Brazil
● In the last 4 years in Brazil there was
– More than 480 papers presented in different
conferences about cloud (not included papers in
journals)
– These papers where in more than 130 conferences

4. Principal Conferences
● Some of the principal conferences on Cloud where Brazil
researchers had publications (total 21):
– SoCC - ACM Symposium on Cloud Computing
– CCGrid - IEEE/ACM International Symposium on Cluster,
Cloud and Grid Computing
– CloudCom - IEEE International Conference on Cloud
Computing Technology and Science
– IEEEECLOUD - IEEE International Conference on Cloud
Computing
– UCC - IEEE/ACM International Conference on Utility and
Cloud Computing

Cluster vs Cloud

Traditional hardware Cluster
 Hardware cost
 Hardware maintenance
 People for maintenance

Cloud Computing
 Without acquisition and maintenance cost
 Minimum staff
 Pay per use

Challenges in applications migration
to cloud

Portability:

Lack of application and code documentation, slow down migration.

Scientific applications have a very specific problem domains.

Migration requires a high level knowlegde of application .

Applications developed without version control or comments creates a
bottleneck in migration (legacy code)

Costs

Porting application code to PaaS.

Number of processing instances

Acceptable time to solution

7. 7
Challenges in applications migration
to cloud

Resources
 Network

Scaling, instance migration, resilience.
 Storage

Local and distributed file systems.
 Processing

Number of instances vs number of processors.
 Applications

CPU-bound, IO-bound, Network-bound.

SIG – Special Interest Group
● Considering the evolution on the research and use of cloud
in Brazil, it is time to create a SIG
● Considering that cloud is a tool, a resource, used by many
different areas, the SIG needs to attend all of them
● Let’s go to SIG-CLOUD
