Taxonomy Survey Of Cloud Computing Systems â€Myassignmenthelp.Com

Question: Discuss About The Taxonomy Survey Of Cloud Computing Systems? Answer: Introducation Virtual Linux server hosting is provided by an instance of Amazon EC2 on AWS, while on Azure it is provided by use of Azure Virtual Machine (Cloud, 2014). IBM Bluemix provides the Linux virtual hosting by use of a Virtual Server and Bare Metal Server. The virtual Linux servers are also provided by use of Amazon Lightsail on AWS, Azure App Service on Azure and by use of a Virtual Server on Bluemix (Varia Mathew, 2016). Storage for the three cloud computing providers business; Virtual machine storage, object storage, Gateways, archival and file storage (Rimal, Choi Lumb, 2009). On Amazon, Object storage is enabled by use of Simple Storage Service (S3), while Azure Blob storage handles objects on Azure platform, and Bluemix Object storage on IBM cloud (Rimal, Choi Lumb, 2009). For virtual Machine Disk Storage, Amazon uses Elastic Block Storage (EBS), while Azure uses Blobs and IBM uses Block Storage. Cold Vault technology is used by IBM Bluemix for long term archival storage, while AWS uses Glacier storage, and Azure uses Cool Storage (Cloud, 2014). All the three service provides storage on relational, NoSQL databases, In-memory data store and data warehousing (Furht Escalante, 2010). For analytics purposes, Amazon uses Redshift data warehousing, while IBM uses dashDB and Azure uses Azure SQL. For virtual machine management, all the three platforms use management consoles and a Command Line management interface (Furht Escalante, 2010). Amazon provides additional management tools such as Service Catalog and OpsWorks for managing server automation. Other management tools include CloudWatch and CloudTrail used by AWS for logging and monitoring, Azure's Log Analytics and Application Insights (Varia Mathew, 2016). Azure AWS IBM Bluemix Ubuntu Open SUSE SUSE Linux Enterprise Red Hat Enterprise Linux Oracle Linux Debian CoreOS CentOS Ubuntu SUSE Red Hat Enterprise Linux Amazon Linux Kali Linux Debian CentOS Ubuntu SUSE Linux Enterprise Red Hat Enterprise Linux IPv4 and IPv6 addressing The three cloud service providers under review; Amazon AWS, Microsoft Azure and IBM Bluemix all support both IPv4 and IPv6 addressing protocols. The default setting on Amazons EC2 is to use IPv4 addressing protocol (Cloud, 2014). IPv6 is operations on Amazon AWS, but when assigned the address is reachable from the internet, as all IPv6 are all public (Cloud, 2014). For an instance configured to use IPv6, it contains both IPv4 and IPv6, which can be used in a dual-stack mode, but require security configuration for each IP type (Cloud, 2014). AWS does not support elastic IPv6, but supports elastic IPv4 (Cloud, 2014). On the other hand, Azure requires that a single IPv6 to be configured and assigned to a given VMs network interface (Wilder, 2012). However, the IPv6 can only be private; a public IPv6 can only be assigned to a load balancer; the DNS on Azure contains both IPv4 and IPv6 (Wilder, 2012). Redundancy and Backup The three cloud computing providers under review provides extensive redundancy, backup and disaster recovery. On Amazon AWS, redundancy and backup is implemented using convectional backup and restore mechanisms, Pilot Light solution which provides redundancy and simple recovery solution, as well as Warm Standby Solution and Multi-site solutions, which ensures business management continuity and recover in case of outage of the primary virtual machines (Cloud, 2014). The AWS Storage Gateway provides means of having snapshots of the live system to be backed up on Amazon S3, which provides near-real-time backup solution (Cloud, 2014). On Azure platform, redundancy is provided by having data backed up in many regions, as datacenters are placed in different locations around the globe (Wilder, 2012). Data and virtual machines are replicated on secondary locations, with the option of having automatic replication of virtual machines, based on policies set by the client (Wilder, 2012). Such backup enables seamless continuity of a business even in case of a region-specific system failure (Wilder, 2012). Like the case of AWS and Azure platforms, IBM Bluemix provides a wide range of redundancy, backup and recovery options. The Zerto Virtual Replication technology on Bluemix enables the backup and redundancy of virtual machines, which facilitates disaster recovery in case of a failure (Gheith, 2016). Other solutions and technologies used by Bluemix include EVault Backup and Veeam technology with provides both automatic backup, replication and restoration capabilities (Gheith, 2016) References Cloud, A.
