You have a video transcoding application running on Amazon EC2. Each instance polls a queue to find out which video should be transcoded, and then runs a transcoding process. If this process is interrupted, the video will be transcoded by another instance based on the queuing system. You have a large backlog of videos which need to be transcoded and would like to reduce this backlog by adding more instances. You will need these instances only until the backlog is reduced. Which type of Amazon EC2 instances should you use to reduce the backlog in the most cost efficient way?

You have recently joined a startup company building sensors to measure street noise and air quality in urban areas. The company has been running a pilot deployment of around 100 sensors for 3 months. Each sensor uploads 1KB of sensor data every minute to a backend hosted on AWS. During the pilot, you measured a peak of 10 IOPS on the database, and you stored an average of 3GB of sensor data per month in the database. The current deployment consists of a load-balanced auto scaled Ingestion layer using EC2 instances and a PostgreSQL RDS database with 500GB standard storage. The pilot is considered a success and your CEO has managed to get the attention of some potential investors. The business plan requires a deployment of at least 100K sensors which needs to be supported by the backend. You also need to store sensor data for at least two years to be able to compare year over year improvements. To secure funding, you have to make sure that the platform meets these requirements and leaves room for further scaling. Which setup will meet the requirements?
您最近加入了一家初创公司,该公司致力于开发传感器来测量城市地区的街道噪音和空气质量。该公司已经对大约 100 个传感器进行了 3 个月的试点部署。每个传感器每分钟将 1KB 的传感器数据上传到 AWS 上托管的后端。在试验期间,您测量到数据库的峰值为 10 IOPS,并且每月在数据库中平均存储 3GB 的传感器数据。当前的部署由使用 EC2 实例的负载平衡自动缩放摄取层和具有 500GB 标准存储的 PostgreSQL RDS 数据库组成。该试点被认为是成功的,您的首席执行官已成功吸引了一些潜在投资者的注意。该业务计划需要部署至少 100K 个传感器,并且需要后端的支持。您还需要将传感器数据存储至少两年,以便能够比较逐年改进。为了获得资金,您必须确保平台满足这些要求并为进一步扩展留有空间。哪种设置可以满足要求?
