Zorluk: OrtaAWS Storage Services

A logistics company needs to migrate 80 TB80\text{ TB} of historical shipping data from their on-premises server room to Amazon S3. The company has a limited network connection of 10 Mbps10\text{ Mbps} and wants to complete the transfer as quickly and cost-effectively as possible. Which AWS service should the company use to perform this data migration?

  1. AWS Snowball Edge Storage OptimizedCevap
  2. B
    AWS Storage Gateway (Volume Gateway)
  3. C
    Amazon S3 Glacier Flexible Retrieval
  4. D
    Amazon Elastic File System (Amazon EFS)

Cevap

AWS Snowball Edge Storage Optimized
AWS Snowball Edge Storage Optimized is the correct service because it uses a physical storage appliance shipped directly to the customer's on-premises location. The data is copied over a local high-speed network and then shipped back to AWS, bypassing the slow 10 Mbps10\text{ Mbps} internet link entirely.

Adım Adım Çözüm

1
Calculate the theoretical transfer time for sending the data over the network.
The time required to transfer 80 TB80\text{ TB} of data over a 10 Mbps10\text{ Mbps} connection is approximately 740740 days.
To determine if a network-based transfer is feasible. The formula is: Time=Total DataNetwork Bandwidth=80 TB×8×1012 bits10×106 bits/second≈6.4×107 seconds≈740.7 days\text{Time} = \frac{\text{Total Data}}{\text{Network Bandwidth}} = \frac{80\text{ TB} \times 8 \times 10^{12}\text{ bits}}{10 \times 10^6\text{ bits/second}} \approx 6.4 \times 10^7\text{ seconds} \approx 740.7\text{ days}
2
Evaluate the available AWS migration services for offline data transfer.
AWS Snowball Edge Storage Optimized is identified as the optimal tool.
Since a network transfer is highly impractical (taking more than 22 years), an offline, physical media transfer service is required to securely and rapidly migrate the dataset.

Anahtar Kavram

AWS Snow Family provides physical devices to transfer large amounts of data offline when network bandwidth is limited.
