2REPORTIntroductionThe cloud storage service is availed by different organizations for maintaining,managing, and backing their data. These data are made available to the organizations over anetwork by the service providers. There are various companies that provide this service to theorganizations among which, Amazon Web Service is a popular one. The organizations mainlyhas to pay for per consumption monthly rate for availing this service that is lower than buildinginfrastructure to support their data system. However, the security of the cloud storage is undercontinuous debate due to some of the issues that recently aroused in AWS. Some of the webservice provided by AWS went down for four hours on September 2015, which caused thecompanies face a tremendous loss and data loss. Some of the websites that faced major loss areNetflix, Slack, Trello, Quora and Business Insider.The following of the report gives an overview of the causation of the issue. It willprimarily focus on the ISO/IEC 27014, which is a certificate that provides information security.The companies utilizes it for monitoring, evaluating, and communicating with the informationsecurity within the organization. The later part of the report provides solution of required foravoiding such issues in future.Causation of the IssueThe outage of September 2017 in AWS was caused due to a problem with Amazon’sDynamoDB metadata service for partitioning. The DynamoDB’s communication ability with themetadata services was critically affected due to a network disruption. This type of situationusually occurs if a single partition is accessed frequently leaving the other partitions unattended.
3REPORTThe issue with DynamoDB was soon resolved that created the actual issue. A number of storageservers simultaneously tried to load their metadata as soon as the DynamoDB was recovered. Itcreated an overload in traffic that caused the metadata service responses to exceed the retrievaland transmission time allowed by storage servers, which caused storage servers to reject andfurther requests. It resulted into shutdown of the servers. However, the effect cataract through theAWS system and dragged down the other services that use DunamoDB for storing their internaltables. Several attempts of increasing the capacity of the metadata to decrease the load failed. Itwas after six hours when the engineers were able to increase the capacity of metadata servicesignificantly and bring back the storage servers to its full operational mode (dailymail.co.uk.2017).SolutionThe disruption occurred can easily be resolved by following one of more proceduresmentioned below.Thefirst methodwas utilized by AWS for solving the issue occurred. It is temporaryinclination of the amount of read or writes capacity for the partitions to overcome the short-termspikes or bursts. The organization needs to reduce the capacity after successfully reducing thework load (Niranjanamurthyet al.2014). Thesecond methodis the process of implementingerror retries and exponential back off. It usually provides longer gap between retires forconsecutive error responses (Amazon Web Services 2017).Thirdly,the organizations shouldorganize the read and write operations evenly across the table as much possible to avoid suchbreakdown (Dimovski 2013).Lastly, implementation of ElastiCache will come handy in the
