The correct option is Place six EC2 instances in a cluster placement group and choose instance types that support enhanced networking. Intelligent tiering automatically optimizes storage costs for unpredictable access patterns without retrieval fees and keeps performance high for hot objects. This design has virtually no infrastructure to manage, scales automatically with usage, and supports consistent month end reporting when you write immutable files and partition or snapshot the data so reports run against a stable view. You can mount EFS from on premises over the Spinlynx existing VPN and mount it on all EC2 web servers so every instance serves the same up to date content.

When a question mentions ephemeral or high local random I/O and the application can rebuild data on replacement nodes pick instance store for cost and performance unless you explicitly need durability or shared access. For on premises NFS compatibility with cloud scale choose File Gateway so clients keep using NFS while objects land in S3 and lifecycle rules handle archival. That option does not preserve existing NFS workflows and does not offer native S3 object lifecycle tiering for active file access. The solution scales independently of on premises hardware and lifecycle rules can move infrequently accessed objects to S3 Standard‑IA, S3 Glacier, or S3 Glacier Deep Archive to lower costs.

This approach preserves existing NFS access while pushing data into S3 so capacity grows without changing client tools and it enables automated tiering to reduce long term storage costs. Lambda supports durations up to 15 minutes so a 55 second job runs comfortably while automatic scaling handles bursts without idle EC2 capacity. It supports multi AZ deployment with automatic failover and replication for high availability and durability and it provides point in time backups and encryption to meet enterprise recovery and security needs. It provides fully managed SMB file shares that can join a self managed Active Directory on premises and it supports Windows native features such as NTFS permissions while allowing multiple Windows applications to access the same share without custom replication or synchronization.

• Learn how internal, conceptual and external database schemas organize storage, logical design, security and client access.
• For a few VPCs choose VPC peering connection to minimize ongoing cost and remember that peering is non transitive so plan pairwise links or use Transit Gateway for many to many scenarios.
• While Jenkins integrates with many alternate build tools such as Gradle and Ivy, Jenkins offers out-of-the-box Maven support.
• It would also introduce lag and complexity with nightly synchronization and would not support concurrent edits safely without a cluster aware file system.
• When you see cross account automation with least privilege and no long lived credentials, look for a role assumed with temporary credentials and require an external ID to prevent the confused deputy problem.

Remember that CloudFront is the service to choose for global caching of live and on demand video and that MediaPackage is for packaging while Global Accelerator and Route 53 address different network or DNS needs. AWS Global Accelerator improves TCP and UDP path performance and provides static anycast IP addresses, but it does not perform content caching or provide HTTP streaming capabilities so it is not a substitute for a CDN. AWS Storage Gateway is a hybrid connectivity service that can front S3 or integrate with FSx for on prem access but it is not the direct native multi AZ SMB file system for EC2 workloads and it would add unnecessary architectural complexity for this migration. CloudFront caches static S3 objects at global edge locations so users in North America, Europe, and Asia fetch content from nearby edges which reduces latency and bandwidth to the origin. When Windows and a self managed Active Directory are required choose FSx for Windows File Server for SMB and AD integration.

Budgets support both actual and forecasted alerts and Budgets actions can automatically apply IAM policy changes to restrict permissions when thresholds are exceeded. For a few VPCs choose VPC peering connection to minimize ongoing cost and remember that peering is non transitive so plan pairwise links or use Transit Gateway for many to many scenarios. NAT gateway enables outbound internet access for instances in private subnets while blocking inbound internet initiated connections so it cannot be used to link separate VPCs together.

Microservices break down monolithic applications into smaller, more manageable components. In the past, organizations were either locked into Java EE-based deployments or development with Microsoft .NET components. The ability for development teams to pick the programming language best suited to the task is a giant benefit of microservices.

This strategy requires a team to support a set of collectors on their network, and in turn, adds more expenses related to the increase of virtual machines. Also, because the collector is close to the other components of the microservices-oriented architecture, it reduces latency between the architecture and the collector. Cloud-hosted microservices users will have to consult with their provider on identifying the best place to host the collector. In a best-case scenario, the machine is located on the same data center rack that hosts the other microservices components. While logging data on the local machine helps improve performance, there is a tradeoff. Learn why GitHub changed the default branch name, what it means for existing repositories, and how the update affects GitHub Pages.

Create a cross account IAM role with only the needed permissions and let the client assume it using the role ARN without an external ID omits the external ID that helps prevent the confused deputy issue when granting access to another account. The client can use the CLI to call AssumeRole with the role ARN and the external ID and then invoke the API with the temporary credentials. Requiring an external ID in the trust policy mitigates the confused deputy problem when a different account or third party is allowed to assume the role. Traffic is directed to the closest healthy AWS Region based on performance measurements and health checks, and endpoint groups let you register Network Load Balancers per Region with fine control using traffic dials and weights. AWS Global Accelerator gives you two static anycast IP addresses that you can share with customers for allow lists and it can also support Bring Your Own IPs. Put six EC2 instances in a partition placement group and select instance types with enhanced networking targets large distributed systems where partitions are isolated on separate racks.

Push Local Project Files to an Existing GitHub Repository

VPC peering connection is the correct choice because it provides private IP routing between VPCs in the same AWS account while keeping ongoing costs low. Place the RDS database in public subnets within a VPC and have office users connect using AWS Client VPN from their desktops is not ideal because Client VPN secures individual client devices rather than the whole office network and hosting the database in public subnets contradicts the goal of minimizing exposure. Remember that in-Region read replica replication is not charged and that cross-Region replication generates data transfer costs so include network fees when planning replicas. For that reason Replicating from a primary DB instance to a read replica in a different AWS Region incurs inter-Region data transfer charges and you should plan for network costs when designing cross-Region read replicas. Route reporting reads to Aurora reader endpoints during heavy reporting windows to protect the primary and avoid running a separate analytics cluster for short periodic spikes. Replicas are designed for read scaling and they are usually more cost effective for periodic reporting spikes than running a separate analytics cluster or permanently upgrading the primary instance.
