Question

In AWS, what is the difference between rebooting and stopping/starting an EC2 instance? Explain it in terms of what happens in each case when dealing with a EBS Volume vs Instance Store volume (i.e. EC2 is created from Instacne Store AMI where you have no visibility to the volume from the AWS console)?

Answer

Rebooting, just reboots the underlying OS, whereas Stop/Start, is done when there is something wrong with the underlying Host hypervisor. Stopping and instance and starting it, could cause the instance to run on another host (i.e. could result in new IP, etc). So in case of EBS Volumes, nothing bad happens (as new instance running on possible new host just gets attached to same EBS volume), but if you have EC2 backed by Instace Store AMI, Stop/Start will kill/delete/wipe the root device volume.

^^ note that when you stop an instance, you don't get charged for compute anymore, but if you are using an EBS backed volume, you do get small storage charges for the EBS volume.

• Shorten field lengths, especially unusually long ones that disrupt the visual flow, and reduce cardinality when reasonable. • Each column should have a unique header; multiple or redundant headers can be merged. • Label the currency type or percentage in the header, not next to each entry. • Remove random cell annotations or consolidate them in an additional column titled “Explanations.” • Fill blank cells with appropriate treatment or leave them blank to indicate unknown or unavailable values. • Confirm that all rows have identical numbers of columns aligning with headers. • If necessary, change the rows to columns or columns to rows. • Merge rows or columns to eliminate empty cells or an emphasis on sparsity of data. • Group associated variables into categories or ranges to facilitate visualization.

Question

In AWS, if you want multiple EC2 instances to share the same directory subtree, you can create an EFS file system and then mount that files system from each EC2 instances. But you also have to configure a Security Group rule for the EFS file system that allows incoming traffic on the [...] port.

Answer

NFS

^^ NFS port is 2049, but you don't have to memorize this as it is provided for you when you add the SG rule for the EFS filesystem
^^^ the source that you add for the SG rule is the SG of the EC2 instances (because you only want the EC2 instances to be able to access the EFS filesystem, not all the world!)

Some basic guidelines for using color in bar charts and graphs include these: • Many companies have presentation guidelines that require that predefined colors (or colors based on them) be used whenever possible. • Choose colors strategically, always keeping the audience in mind, and use compatible colors (those in close prox- imity on the color wheel) rather than competing colors (those on opposite sides). • Use the same color throughout the display to represent the same variable and graduated shades of one color to make a multiple-bar chart easy to scan and follow. • Because the color red depicts business losses, using it to graph negative earnings or growth can be productive, but red should not be used to display positive results. • Black ink should be used for text on a light background; if a black background must be used, white text should be used, not another light color.

Best practices for combining multiple displays into a series of displays include these: • The series of smaller graphs should be consistently dis- played. • The series should be arranged to highlight the identified relevance of the comparison. • The series should be sequenced as the variable is ordered (lowest to highest, oldest to youngest, and so forth). • Gridlines should be used sparingly and only if space limi- tations require separation to assist in following the series.

Question

In AWS, you can group EC2 instances into Placement Groups that determine how they are distributed over different racks within differnt data centres. There are three types of Placement Groups: [...] , Spread and Partitioned.

Answer

Clustered

^^ Clustered Placement Groups are for a set of EC2 instances that communicate a lot with each other and you want low network latency between them, so you want them in the same Availability Zone and as close together as possible (i.e. on the same rack).
^^^ Spread Placement Groups are for a set of EC2 instances that do not communicate much with eachother (i.e. low network latency is not an issue) but they each do critical workload that is a replication of each other, so you want them on differnt racks, possibly spread across multiple AZs. For Clustered Placement Groups think individual EC2s!
^^^^ Partitioned Placement groups, place EC2 instances into different partitions, each of these partitions is then in turn spread across multiple racks, possibly across multiple AZs. This is for HDFS, Cassandra usecases.
