When launching an Elastic Compute Cloud instance with Amazon Web Services, you need to select a type and size for the instance. This selection will dictate how many CPU cores are available, how much memory is available and how much storage is available for the virtual machine. What happens if your initial selection was wrong for the task at hand?
Are EC2 Instances Resizable? An AWS EC2 instance is resizable if the instance is an elastic block store backed instance. The instance type or instance family can be updated meaning the number of cores, amount of memory, amount of storage, and other aspects of the instance can all be changed.
There are a lot of small businesses that need to use some amounts of computer or server resources in order to run and maintain their business. A lot of the time these small businesses will use a smaller local or regional technology company to fulfil those needs. At some point these small businesses may want to consider using a cloud service like Amazon Web Services.
Any small business should consider using the AWS cloud to host their technical needs as it can save large amounts time and money while helping bring goals into reality more quickly. The AWS cloud will be more reliable and have more technical capability than what a small business can do on their own.
When choosing a cloud provider, one important thing to consider is how reliable that cloud providers services are. Even if the cloud provider offers compelling services, if they aren’t reliable, they aren’t worth using.
Is AWS Reliable? Amazon Web Services has had only twelve major service events that impacted AWS service availability between June 8, 2011 and August 23, 2019 as shown on their post event summaries page. This is an incredibly reliable cloud provider and their services can be highly trusted to remain available.
Before discovering a cloud environment like Microsoft Azure, most small businesses will either self host their technology and applications, use a local provider to host, or pay for co-location of their systems. However, when first learning about a cloud like Microsoft Azure, a small business may wonder if the switch is worth the effort?
Microsoft Azure is definitely worth considering for a small business as there may be savings in time, money, and time to market for many projects they are hosting. The small business will also get to rely on the expertise Microsoft has in this area instead of requiring in house knowledge.
Microsoft has created and freely provided a vast amount of documentation for their Azure services. Over and above this they have prepared many tutorials, courses, and exams to help their Microsoft Azure customers easily become proficient in any of the available services.
Amazon Web Services provides an extensive amount of documentation resources for all of their services. They also offer free digital training, in class training and private training. On top of this there are a large amount of learning paths made available for most end user use cases.
Microsoft Azure is a cloud environment which provides access to a vast array of services to accomplish many tasks. Many of these services do not require any programming skills from the end user. This includes storage services, machine learning services, search services, migration services and more.
Amazon EC2 is a cloud based service which gives customers access to a varying range of compute instances, or virtual machines. Amazon EMR is a managed big data service which provides pre-configured compute clusters of Apache Spark, Apache Hive, Apache HBase, Apache Flink, Apache Hudi, and Presto.
Spot instances should not be used with applications or systems that are unable to handle intermittent or random failures of nodes. Processing tasks that have long run times to complete their work with no external partial saving mechanism should also avoid being run on spot instances.
