How do I choose the right data structure in C++11?

Choosing the right data structure depends on your specific use case. Are you looking for fast access, insertion, or deletion?

I need fast access and frequent updates.

In that case, consider using a std::vector for fast access and a std::deque if you need efficient insertions and deletions at both ends.

What about when I need to maintain a sorted order?

For maintaining a sorted order, you might want to use std::set or std::map, as they keep elements sorted and allow for efficient insertions and lookups.

Are there any performance considerations I should be aware of?

Yes, each data structure has its own performance characteristics. For example, std::vector has fast access but can be slow for insertions in the middle, while std::list allows for fast insertions but has slower access times.
